- adaptations for x64 build
- sync with N++ interface files 7.5.4
- updated scintilla interface to the one used for 7.5.4 which is version 3.5.6 + small fixes + wrapper generation corrections, updates (thanks to @ClaudiaFrank)
- reduced compiler warnings
- used plain python 2.7.14, without the modifications from fork https://github.com/bruderstein/python, reintroducing dependency to MSVCR90.dll
