update docs for 0.14

[belevtsoff]

Add suggestions to the following list as new features are implemented:

• re-run autodoc generation to account for API changes
• mention component renaming feature in tutorial (maybe also explaining the FilterStack usage)
• document the new filter implementation
• document the new "wavelet transform" feature and selection methods
• force_recluster_on_update argument
• release notes
• outdated README
• mention changes in the feature naming convention

@belevtsoff could you document the new filter implementation?
