Merge lp://qastaging/~unity-2d-team/unity-2d/unity-2d-shell-shaped-testability-shapetests into lp://qastaging/~unity-2d-team/unity-2d/unity-2d-shell

* inputshapemask.cpp:19 always add a trailing slash to unity2dDirectory() as it doesn't do that internally (see bug 918669)
* one thing I'm afraid of: animating the launcher shape looks unnecessary and a resource drain, could we have just the "fully-on-screen" shape, enabled or disabled as soon as the launcher is supposed to be shown?
* unity2ddeclarativeview.cpp:161 any reason for the #include there?

* getshape.cpp:72 unnecessary space before semicolon
* getshape.cpp maybe use QUrl::fromLocalFile / toLocalFile to handle things like ~?
* getshape.cpp doesn't seem to handle masks, just rectangles?
* input_shaping.rb:9 I'm sure Gerry will be pleased ;)
* input_shaping.rb:35 open_window_at has been refactored into a separate TmpWindow class, see autohide_show_tests.rb
* input_shaping.rb:68 maybe use a constant like other UNITY_2D_* do?, especially if #{pwd} is really $PWD
* input_shaping.rb:92 says "Launcher Autohide and Show Tests"
* input_shaping.rb:92 maybe abstract the constants to run-tests.rb? we do have the launcher width in launcher tests, too, might make sense to only have them in one place
* input_shaping.rb:94 DASH_HEIGHT_COLLAPSED looks unused?
* input_shaping.rb:128 says Launcher, should be Shell?
* input_shaping.rb:188 why D-Bus? do we actually need / want to expose that over D-Bus?

Please can you add a comment of the following form to each test case?:

# Test case objectives:
# * Check the Launcher position on Empty desktop
# Pre-conditions
# * Desktop with no running applications
# Test steps
# * Verify something
# * Click a button
# * Verify this happens
# Post-conditions
# * What non-unity2d thing should exist at test end
# References
# * None (lp bug number?)

This helps show what test cases need to be altered for future changes, and lets non-experts analyse the coverage of our test-suite.

And one more thing: "desktop_geometry" could be added to the Ruby XDo library
