Update ep1 module
Bug 923358 - Fix missing graph in framediff view for startup tests;r=davehunt
Bug 920749 - Make synchronizing time work on FirefoxOS;r=davehunt

Do this by moving the device initialization/cleanup code outside of the
tests, where the synchronization code lives.
Bug 924535 - Documentation improvements;r=davehunt
Bug 924535 - Improve documentation for getting individual results;r=davehunt
Bug 888103 - Start apps by "pressing" on their icon on homescreen;r=davehunt
Bug 922770 - Set stable frame threshold to be less than 4096 pixels;r=davehunt

Turns out that 2048 was too few for certain cases (e.g. a scrollbar
transitioning out) where things aren't actually changing very much.
Bug 927122 - Run apt-get update before installing stuff in travis;r=davehunt
Bug 927122 - Remove obsolete comment about irc being broken;r=davehunt
Bug 917404 - Use entropy of frames for calculating differences on pointgrey cameras;r=davehunt
Bug 917366 - Make getdimensions compare against earlier frames;r=davehunt
Bug 917404 - Consolidate and clarify capture analysis;r=davehunt

We seperate logic in get-metric-for-build and update-dashboard for setting
different thresholds for startup, input, and animation analysis. This caused
things to sometimes break when an underlying component changed and one program
was modified but not the other. Fix this by consolidating all the image analysis
code inside the "eideticker" module (we'd already started to do this).

Also, we used the same language for the pixel threshold when creating the raw
framediffs as we did for getting statistics from the framediffs, which
was pretty confusing. Fix this by instead setting an option to this function
to filter out small changes (which is all ever did anyway).
Bug 923986 - Wait for navigator online event instead of sleeping in b2g tests;r=wlach
Bug 928115 - Fix various minor issues with pointgrey capture utility;r=davehunt
Bug 928115 - Support Flea3 FL3-U3-13Y3M + variable framerate in point grey capture program;r=davehunt
 Bug 933324 - More documentation improvements;r=davehunt
Bug 917366 - Add option to output capture area overlay when retrieving dimensions. r=dhunt
