0.3.5 -> 0.5.1 migration madness

There is a bug in the migration code for Greasemonkey 0.5.1 which is affecting some windows users. 0.5.2 fixes this issue, and has been circulated through the mailing list and is looking good, but I won't be able to post it until tonight.

If you want to fix your 0.5.1, I don't think it's a good idea to edit the profile files directly unless you really know what you're doing. Instead, these steps should fix most people's corruption.

• Shut down Firefox.
• Find your profile directory
• Move profileDir/extensions/{e4a8a97b-f2ed-450b-b12d-ee082ba24781}/chrome/
  greasemonkey/content/scripts/ to profileDir/scripts.
  
• Remove profileDir/gm_scripts if it exists
• Rename profileDir/scripts to profileDir/gm_scripts
• Restart Firefox
