Campbell Barton 51dcbdde03 use 'const char *' by default with RNA functions except when the value is flagged as PROP_THICK_WRAP. 
Also use const char in many other parts of blenders code.

Currently this gives warnings for setting operator id, label and description since these are an exception and allocated beforehand.
