Refactor Search.py

[Nihilate]

Search.py is a bit of a mess in terms of testability, readability, extendability and code reuse.

Goals:

• Split it up so that it only does what it should do (return search results) instead of returning formatted comments
• Move the common "search web" algorithm into a single function instead of replicating it everywhere
• Improve the "search web" algorithm so that it actually loops through all possibilities (might want search results cached before attempting this to avoid blasting the database sites too much)
• Find a way to make the algorithm make more sense (maybe it just needs to rely on better documentation)
• Unit test the shit out of it
