Minor bugfixes to vss2svn.pl:
- fix reading version numbers greater than 9.
- handle "--vssproject $/" correctly
- remove "use diagnostics", which only confuses regular users
- print startup message so doesn't appear to hang on large projects
- passing an invalid project is a fatal error
- prevent SQL quotes from appearing in users prompt
Added devnotes.txt for my own use
Add _vss2svn directory to ignore list for ease of testing
