IDA Pro 6.5 support

What's new:
- Proper multi-threaded support 
- Better PyObject reference counting with ref_t and newref_t helper classes
- Improved the pywraps/deployment script
- Added IDAViewWrapper class and example
- Added idc.GetDisasmEx()
- Added idc.AddSegEx()
- Added idc.GetLocalTinfo()
- Added idc.ApplyType()
- Updated type information implementation
- Introduced the idaapi.require() - see http://www.hexblog.com/?p=749
- set REMOVE_CWD_SYS_PATH=1 by default in python.cfg (remove current directory from the import search path).

Various bugfixes:
- fixed various memory leaks
- asklong/askaddr/asksel (and corresponding idc.py functions) were returning results truncated to 32 bits in IDA64
- fix wrong documentation for idc.SizeOf
- GetFloat/GetDouble functions did not take into account endianness of the processor
- idaapi.NO_PROCESS was not defined, and was causing GetProcessPid() to fail
- idc.py: insert escape characters to string parameter when call Eval()
- idc.SaveFile/savefile were always overwriting an existing file instead of writing only the new data
- PluginForm.Close() wasn't passing its arguments to the delegate function, resulting in an error.
