engine / branding: introduce sass for css compilation

Introduce sass via libsass [1] / libsass-maven-plugin [2][3],
and move ovirt.brand into a maven project in frontend/brands.

Sass is a css pre-processor that brings us css compression,
allows breaking up css into smaller files (called partials)
without runtime performance penalties, and allows us to
move away from GWT css solutions (whereby css ends up baked
into generated JavaScript).

Follow-up patches will convert our current css files to well-
structured and organized sass files, using partials, variables,
etc.

[1] https://github.com/sass/libsass
[2] https://mvnrepository.com/artifact/com.github.warmuuh/libsass-maven-plugin/
[3] https://github.com/warmuuh/libsass-maven-plugin

libsass is platform-specific, written in C/C++. The Maven
plugin uses jsass [4] to interop with libsass.

jsass uses the "git submodule" feature [5] to pull in libsass code,
effectively avoiding the platform-specific dependency on libsass.
Therefore, jsass is self-contained Sass impl. that contains
all platform-specific libs (Windows .dll, Linux .so, etc.) in
its distributable JAR file.
