RubyGems upgrade, File Manager upload revert, misc bug fixes

A few fixes have trickled in over the past two days in addition to the two listed below:

• Changed: Upgraded RubyGems to 1.0.1
• Fixed: revert File Manager “Upload” button that was previously missing (oversight, honest)

Older fixes from the last few days bundled into the blog post:

• Fixed: editing Majordomo configuration resulted in incorrect permissions/ownership combination (660, admin user/group)
• Fixed: next SQL backup date should use today as base instead of the next_date field
