Improve performance

[andrewghobrial]

Very small change, but huge performance improvement in this PR.

Two changes:

1. Use angular AOT compiler improves processing performance greatly on front-end
2. The angular static output is very large (The main.f361828dc635e1980674.js ~3.75 MB). Using gzip to serve static files reduces this file from 3.75 MB to 866 KB.

I also changed the base path of the static files to be "." (current working directory). This uses the current working directory instead of the location of the binary to determine room path. This helps when an IDE runs your binary in a temp folder, but shouldn't break anything.

BTW, the gzip will only affect CF and AIO deployments.. May be useful to check if this is already being done in other deployment modes

LGTM. The other deployments are fronted by nginx, which does the gzip.
