AutoPkg 2.8.1 RC3

Fixes:

• Recipe map now correctly rebuilds after adding a new repo (#868)
• Unit tests now run on the dev branch first
• Fixed some various lint issues
• Fixed an issue where you could you not add or remove recipes if RECIPE_SEARCH_DIRS was missing from the preferences; it now populates the default folders.

Known Issues:

• Preferences store relative/local paths inconsistently. Some are stored in preferences as ~/Library/AutoPkg, others convert to an absolute path upon preference storage like /Users/nmscpadden/Library/AutoPkg.
• You cannot run a recipe not in the recipe map by using a shortname in the local directory. You must use the absolute path to a recipe not in the recipe map.
• AutoPkg search is still wonky; this will be addressed in the next release.
