First stab at turning "banners" into generic filters
Get rid of banner from body options
Need to return the filter's return value
Add filter API to Transaction
Add unit tests for filtering stuff
Only test against first bit of content-type line
Add transaction docs
Fix undefined this
More idiomatic way to juggle this
Add encoding param to filters
Move code around
Merge pull request #739 from chazomaticus/filters

add body part search/replace, change bannering to use it
