Fix Windows build using Urho3D as external lib in Release config.
Detected by Travis CI build. With this change, FindUrho3D module should be able to find Urho3D libs in the following scenarios:
- only debug version is available
- only release version is available
- both debug version and release version are available

Request CI build to use a Release build configuration [ci package].
For Travis CI - fix packaging for iOS platform. [ci package]
Attempt to fix doxygen not able to find dot on OSX build environment.
Get rid of some warnings when loading the editor
remove shameful editor bubblesort
For Travis CI - misc. tweaks. [ci package]

- Perform shallow clone when building site documentation to speed up cloning process.
- Perform unshallow pull when packaging so that 'git describe' gives correct commit count since last tag.
- Only perform packaging when all the previous steps are successful. Reduce chances of binary package with not up-to-date documentation.
- When packaging for iOS platform, generate the documentation quietly (no stdout but still stream error to stderr).
For Travis CI - fix commit message parsing that contains quotes.
Look 'here' [ci package]
