More fixes

 * don't run convert.ly on windows.  The process fails for an
   unknown reason.

 * remove some windows references

 * tmpPath does not store the path from the last time ly2video was
   run.  Since the temporary directory name is random, there's no
   point in deleting 'old temporary files'.

 * tmpPath was using RUNDIR for some strange reason.  Though at
   execution time, it's "" which leaves just the temporary
   directory and the desired subdirectory name to join.
