Fix a hack implemented in wxEnumProperty::ValueFromString_ and wxEnumProperty::ValueFromInt_ functions.

Browse Source 
wxEnumProperty code is refactored in order to fix a hack which purpose was (apparently) to bypass constness of these functions by caching determined indices in wxEnumProperty::ms_nextIndex static member variable for further processing. (Unclear concept of using this static member was referred in http://trac.wxwidgets.org/ticket/12779#comment:9)
Now, determined index is returned to the caller and processed there if necessary and hence caching of this index is not necessary.
