Client side caching
Merge remote-tracking branch 'origin/master' into feature/clientcache

Conflicts:
	PowerPlanner/src/com/powerplanner/DatabaseFileFInder.java
	PowerPlanner/war/Scripts/map_helper.js
Included underscore.js, fixed some js errors with caching, updated
servlet to grab bounds from file name properly
Extracted marker logic into separate js file
Increased map transparency. Fixed data fetch timer.
Finished cleaning up initializing by moving location search init to
separate file and logical area. Removed markers when searching location.
Fixed bug where searching from start page would only load default
location. Pressing enter while entering a search location in the start
page brings user to map page.
