 This patch adds the ability to specify the coordinate reference system in
 the datasourceUri for memory and delimited text providers.

 The main intention in this is to allow plugins to create these providers
 with the CRS predefined, so that regardless of the QGIS default providers
 settings the layer can be created without displaying a reference system
 dialogue to the user.

 Other changes made as part of this:
 QgsCoordinateReferenceSystem string constructor has been generalised to
 allow strings such as "epsg:1234" as alternative to WKT
 QgsMemoryProvider datasourceUri can also specify spatial indexing and
 attributes
 QgsMemoryProvider and QgsDelimitedTextProviders uri's are encoded and
 decoded using QUrl rather than building as QString, to ensure reliable
 encoding of special characters
 QgsDelimitedTextProvider UI tidied up to correctly remember delimiter
 settings in QSettings
