CraftGuide

UI:
- Added a busy spinner when there is an ongoing background task (currently loading
   recipes or text-searching the item list). Replaces the row count when appropriate.

Themes:
- Animation texture type. Uses a list of frames, each of which have a duration
   and a source texture (it composes with other texture types!)
- Parameters can be set up to support unit suffixes. For example, a frame duration
   could be specified as 200ms, 4 ticks, 0.2 second, or just 0.2.
- Finally support source images that are not 256x256 pixels. It would load them
   without issue before, but would treat coordinates as if it were 256x256 still.

API:
- Added a few methods to the RecipeTemplateBuilder; should cover some missing
   use-cases (ThaumCraft aspects come to mind, without resorting to the hack of
   dummy items for essence types). They are currently unimplemented, existing
   largely to start ironing out thoughts

Build script:
- Exploring a "publish to website" option. Current script is a .bat file, and
   a few private details have been removed from it. The script uses PuTTY's pscp
   to upload a version-named directory with jars and a changelog, appends an
   entry to a pseudo-JSON text file, and updates the server's version.
- At some point, I want to have a download page on my personal site, but that
   will have to wait until I set up HTTPS (it would be irresponsible to serve
   executable code via HTTP, especially to an audience as broad as Minecraft's)
- That upload will generally be in addition to publishing to Curse, and is
   more intended to replace how I used to mirror releases to MediaFire and/or
   Dropbox for redundancy
