AkelPad CodeSvn

Added: possibility to use x86 and x64 version with the same settings. For this:
- 64-bit AkelPad.exe rename to AkelPad64.exe. This name is used by AkelUpdater
to update 64-bit version.
- 32-bit AkelPad.exe and 64-bit AkelPad64.exe are in the same folder.
- create a folder "[AkelPad]\AkelFiles\Langs64\" for 64-bit dll files.
- create a folder "[AkelPad]\AkelFiles\Plugs64\" for 64-bit dll files.
Settings of all plugins will continue to be stored in "[AkelPad]\AkelFiles\Plugs".
