  wxGUI: Add new mapset action to data catalog (#731)

* Created GenericMultiValidator to check for several conditions: 1) legal name 2) mapset 'ogr' should not be created as reserved word and 3) mapset already exists. All validations are done in NewMapsetDialog.
* Simplify code in gis_set.py as most functionality moved to NewMapsetDialog.
