[PATCH v2] ui-shared: split repository link into directories

The only missing feature from gitweb: clickable any directory in between. It's
very handy, if you have lots of repos (local AOSP repositories).
If you don't like it hardcoded, I can prepare patch with configuration option.
v2: minor cleanup
