Roll DEPS to new android_tools revision with Android SDK 19 / K release.

This should not break anything as the old SDK (android-18) and build-tools, etc.
was not removed in the new revision. Only android-17, which is no longer being,
used has been remvoed.

Plan is to land this, make sure nothing breaks and then we will update the
android sdk version to android-19 along with build-tools version, etc.

Makes it possible to undock a vertically stretched panel.
This CL fixes (and adds a test for) both causes - the panels getting attached to the shelf when they are resized while docked and windows not being restored to their original pre-docking height when their width was adjusted while docked.

[rAC, OSX] Fix menu button placement.

MenuButton was placing the popup menu too far away from the button for
buttons with sizes different from toolbar buttons. Experimentation
yields that it is placed correctly for a button height of 19px and
needs to be placed differently based on button height.

CC: Set a reasonable raster task limit for perf-testing.

This is much higher than average android platform, which
will keep our perf tests on the strict side.
