r9738 compile error with wx3.0-trunk

[Jenna]

I get the followinhg error with wx3.0 trunk on my linux system (64bit gcc 4.:

/home/jens/codeblocks-build/codeblocks.git/src/sdk/ccmanager.cpp: In function 'int CCManagerHelper::CallTipToInt(const wxString&, int)':
/home/jens/codeblocks-build/codeblocks.git/src/sdk/ccmanager.cpp:72:28: error: ambiguous overload for 'operator^' (operand types are 'int' and 'wxString::const_iterator::reference {aka wxUniChar}')

Casting the (*itr) to int makes the error go away, but as I don't know what this function does, I don't know if this is the corect fix or does something really harmful.

@Alpha and other devs more familiar with CC could you please look into it ?

That is the correct fix.
(The function is used to store a dictionary between calltip context, and the previously user selected calltip page.  I choose to store an int (hash value) instead of the full strings, because CCManager has no need to waste memory duplicating all displayed calltips.)

Edit: Fix committed.
