Research tab, smaller tweaks

Additions:

• Added Journey Mode research editing.
  You can now add/remove researched recipes.
• Added a Master Mode accessory slot.
  Expert Mode accessory slot now also shows correctly for Journey Mode.
• Added tooltips for a handful of buttons.
  Possibly a few years a late, but still.

On offline version:

I'm still researching the options for making an offline version of Terrasavr in light of not being able to compile a new Flash version. This may take a little bit.
