Android: Avoid caching the same class twice.

The class name scheme can be separated by '/' or '.', if both formats
where used we would end-up caching those classes twice.

QMacStyle: Fix default button look on Yosemite

The default button has different text color on OS X 10.10, and
doesn't pulsate anymore.

We first make sure we don't start any animation for default buttons.
Then, we set the right text color in the attached palette, which
implies making a copy of the style option object. This increases the
size of this patch but keeps things sane. (It's also more concise than
the QGtkStyle approach that consists on duplicating QCommonstyle's
code for rendering CE_PushButtonLabel).

QMacStyle: Fix QTabBar appearance on Yosemite

The selected tab text color should be white except when the
window is not active. Also, no text shadow should be rendered
in any case. Finally, there's no need to move the tab shape up
anymore.

Avoid crash if querying device that has gone away

A device removed very fast after being inserted might disappear while
we are still seting it up. We must therefore check if we indeed still
get a matching device
