BLD: update scikit-bio dependency to >= 0.2.2, < 0.3.0

With scikit-bio 0.2.2, deprecation warnings are reported via `DeprecationWarning`. These are silenced by default in Python 2.7+, so this should hide the warnings from QIIME users. They will still show up in QIIME's unit tests.
MAINT: fixes #1723
MAINT: fixes #1671
Add pandas, gdata, burrito, and burrito-fillings info to print_qiime_config.py

Related to #1718 (still need to figure out burrito-fillings version info).
