Merge pull request #1 from mzagozen/keywords

Properly implement div keyword searches.
chrome webstore doesn't like comments in messages.json
don't hide all #banner elements
finance.si support
multilingual support for page action icon
slovenian support
Forgot that CSS attribute selectors are case sensitive :)

Added :attrContains("attr|value") case insensitive replacement for [attr*="value"].
Keyword matching now works, although the DOM is searched multiple times
(zepto does not support complex selectors containing multiple filters).
Properly use regular expressions when looking for confirmation string.
Finance.si is being tricky by offering to opt-out after we've opted-in :)
