gsdx:windows: Handle shader dialog filenames properly 

The shader dialog filename handling code had several buffer overflows
and also did not handle non-English filenames well.

Fix the filename handling by storing them as UTF-8 in the ini and
converting them to/from UTF-16 as necessary, and also fix the buffer
overflows.
