config explicitly.

@property QtMvvm::MessageConfig::type

@default{`MessageConfig::TypeMessageBox`}

The type determines what kind of dialog is show. The type is a general category of dialogs. The
MessageConfig::subType is used to set the final type of dialog shown. It's interpretation
depends on the type used.

It is possible to define your own types, but that means you have to customize the presenters to
add support for those dialogs.

The types supported by default are:

- MessageConfig::TypeMessageBox
- MessageConfig::TypeInputDialog
- MessageConfig::TypeFileDialog

The subType is a finer specification of what kind of dialog to show. It depends on the
MessageConfig::type that is used. The possible valid subtypes depend on the MessageConfig::type
used.

It is possible to define your own subtypes, but that means you have to customize the presenters
to add support for those dialogs.

The subtypes supported by default are:

- For MessageConfig::TypeMessageBox:
	- MessageConfig::SubTypeInformation
	- MessageConfig::SubTypeWarning
	- MessageConfig::SubTypeCritical
	- MessageConfig::SubTypeQuestion
	- MessageConfig::SubTypeAbout
- For MessageConfig::TypeInputDialog:
	- The name of the type to get an input value for, e.g. `QString`, `int`, ...
- For MessageConfig::TypeFileDialog:
	- MessageConfig::SubTypeDir
	- MessageConfig::SubTypeOpenFile
	- MessageConfig::SubTypeOpenFiles
	- MessageConfig::SubTypeSaveFile

@var QtMvvm::MessageConfig::TypeMessageBox

<b>Value:</b> `"msgbox"`

Shows a generic message box with a title and primary text to inform the user of some kind of
event or ask him a question. The MessageConfig:subType is used to determine the kind of
message to show:

 Message Type	| subType value
----------------|---------------

 Warning		| MessageConfig::SubTypeCritical
 Critical Error	| MessageConfig::SubTypeQuestion

The widgets implementation does support a few extra properties for this type:
- modal (bool = true), configure application modality
- windowTitle (QString), the window title
- details (QString), the message box details box
- checkable (bool = false), gives the messagebox a small checkbox
- checkString (QString), the string to display for that checkbox

/*!
@var QtMvvm::MessageConfig::TypeInputDialog

<b>Value:</b> `"input"`

Shows a generic input dialog with a title and a short label, together with some kind of edit
view in order to input a single value. The datatype to get as well as the kind of input view
to create is determined by MessageConfig:subType. Theoretically, and type that can be passed
via QVariant can be used as input value. However, only for the most common types do default
edit views exist. In case you want to use types not present in the list below, you need to
create edit views yourself

 Type					| Widgets edit					| Quick edit	| Quick delegate
------------------------|-------------------------------|---------------|----------------
 bool					| QCheckBox						| CheckBox		| BoolDelegate
 switch					| -/-							| Switch		| SwitchDelegate
 QString, string		| QLineEdit						| TextField		| MsgDelegate (*)

 QDateTime, date		| QDateTimeEdit					| -/-			| -/-
 QFont					| QFontComboBox					| FontEdit		| MsgDelegate
 QKeySequence			| QKeySequenceEdit				| -/-			| -/-
 QUrl, url				| QLineEdit with QUrlValidator	| UrlField		| MsgDelegate
 selection, list		| QComboBox						| ListEdit		| ListDelegate
 radiolist				| -/-							| RadioListEdit	| -/-
 action (settings only)	| QPushButton					| -/-			| ItemDelegate

(*) The MsgDelegate is used for any type but the ones that have explicit delegates. It will
show a dialog with an input of the "Quick edit" column

The following types have special properties as well:

- QString, string:
	- `regexp`: A regular expression pattern (QString) to be used as input validator for the
text
	- `patternOptions`: QRegularExpression::PatternOptions as options for the regular
expression
- QUrl, url:
	- `allowedSchemes`: A QStringList with allowed schemes for the URL
- selection, list, radiolist:
	- `listElements`: A list of elemets the user can select from. Can either be:
		- QString elements: They will serve as display value and returned value
		- QVariantMap elements: A map containing the following values:
			- `name`: A QString shown to the user to select
			- `value`: A QVariant value that is returned instead of the selected name

MessageConfig::NoButton if close by another reason. The pressed button should be one that was
