Need to implement as import patterns for type signature search

[deadfoxygrandpa]

Right now, if you import a module as another name, it confuses elm-oracle. I can parse import statements on my own and work around this to make the behavior correct.

elm-oracle can handle this, but I need it to be server based or something because the latency is too high calling a new process every time the cursor moves. Will revisit later.
