Christian Dywan 3e60f4424b Introduce Automatic user agent and allow quirks 
The new Automatic user agent is meant to pick the string
that websites most likely check for. Right now this is
Safari. Quirks built-in to WebKit are also used.

The separate Midori identification has no quirks.

/**
* katze_property_proxy:
* @object: a #GObject
* @property: the name of a property
* @hint: a special hint
*
* Create a widget of an appropriate type to represent the specified
* object's property. If the property is writable changes of the value
* through the widget will be reflected in the value of the property.
*
* Supported values for @hint are as follows:
* "blurb": the blurb of the property will be used to provide a kind
* of label, instead of the name.
* "file": the widget created will be particularly suitable for
* choosing an existing filename.
* "folder": the widget created will be particularly suitable for
* choosing an existing folder.
* "uri": the widget created will be particularly suitable for
* choosing an existing filename, encoded as an URI.
* "font": the widget created will be particularly suitable for
* choosing a variable-width font from installed fonts.
* Since 0.1.6 the following hints are also supported:
* "toggle": the widget created will be an empty toggle button. This
* is only supported with boolean properties.
* Since 0.1.8 "toggle" creates GtkCheckButton widgets without checkmarks.
* Since 0.2.0 the following hints are also supported:
* "font-monospace": the widget created will be particularly suitable for
* choosing a fixed-width font from installed fonts.
* Since 0.2.1 the following hints are also supported:
* "application-TYPE": the widget created will be particularly suitable
* for choosing an application to open TYPE files, ie. "text/plain".
* "application-CATEGORY": the widget created will be particularly suitable
* for choosing an application to open CATEGORY files, ie. "Network".
* "custom-PROPERTY": the last value of an enumeration will be the "custom"
* value, where the user may enter text freely, which then updates
* the property PROPERTY instead. This applies only to enumerations.
* Since 0.4.2 mnemonics are automatically stripped.
* Since 0.2.9 the following hints are also supported:
* "languages": the widget will be particularly suitable for choosing
* multiple language codes, ie. "de,en_GB".
* Since 0.3.6 the following hints are also supported:
* "address": the widget will be particularly suitable for typing
* a valid URI or IP address and highlight errors.
* Since 0.4.0 the following hints are also supported:
* "days": the widget will be particularly suitable for choosing
* a period of time in days.
*
* Any other values for @hint are silently ignored.
*
* Since 0.1.2 strings without hints and booleans are truly synchronous
* including property changes causing the proxy to be updated.
*
* Since 0.2.1 the proxy may contain a label if the platform
* has according widgets.
*
* Return value: a new widget
