Migrate searches to use client side collection

[lokenx]

This seems like the appropriate way to do the API search. The search results don't need to ever hit the server as they're only temporary, the movie they choose is only one that needs to be written to server.

Also, because this is being put into a collection I should be able to display a simple search or loading animation/text while search is happening. OMDB searches are typically fast, but on occasion they aren't instantaneous and the user has no way of knowing if their search went through or not.

Completed as of last commit (c839e69). I did a whole bunch out of order because I just coded not thinking to commit so it's super unsafe to revert to any of those commits done at same time, the only one I'd trust is the last one linked above (even though it has nothing to do with this issue).
