EXT-3441: Support various substitutions for Search URL.

The search URL is now specified in app_settings/settings.xml (instead
of in floater_search.xml), and it is now defined more flexibly with
support for various substitution strings, such as [QUERY], [AUTH_KEY],
[MATURITY], [GODLIKE], etc.

I pulled the common substitution code out into a new static method,
LLWeb::expandURLSubstitutions(). This provides support for common
strings like [VERSION], [CHANNEL], [LANGUAGE], [OS], etc. The Help and
Home sidetray code has been updated to use this new function, to avoid
replicating this behavior 3 times.

I also cleaned up the app_settings/settings.xml file and removed the
old search keys of: SearchURLDefault, SearchURLQuery, and
SearchURLSuffix2.
