WineTestBot changes

[Greg Geldorp]

Updates to the test bot:

- Improve log parsing and error reporting
- Send notification email on job completion
- Run winetest64-latest.exe on 64-bit machines
- Show warning message if job is submitted without command line arg
- Attempt to display times in users own timezone
- Add possibility to set WINETEST_DEBUG and WINETEST_REPORT_SUCCESS env vars

The code (LGPL) is now hosted on SourceForge in the "wine/winetestbot" git repository.
