* Define Enums for sqrat
* Add a function to get the current call stack
* Temporary add stack info to wrong type error in sqrat
* Sqrat handles now wxString automatically

every function expecting a wxString can now handle wxStrings and normal squirrel strings, without the need of creating a special "translating" function
Still needs testing, and if it works, remove old code
* Update wxString

 * Use the stack handler to throw errors within wxSquirrel functions
+ Add GetChar, AddCha, and Find to the binding
* More informative errors in scriptwizard
* remove unused variable
