Iconfont icons are of no value to screenreader users; in our case,
they get alternative text. By adding 'aria-hidden="true"' to the
<span> holding the iconfont icon, we avoid the screenreader trying
to announce the iconfont icon.
- Only fire JS equal heights if flexbox is not supported
- Add flexbox styles for backend sections that used to use
JS based equal heights
- Use Modernizr's flexbox detection to use the old styles
as a fallback for non-flexbox browsers
- Generate new oldie stylesheet
- Do not use .clearfix with flexbox (Safari doesn't like it)
- Apply IE11 fix for flexbox, see goo.gl/pglrbm

Moved firing the syncHeights plugin to a seperate function in the
serendipity namespace because it needs to be fire onclick for the
plugin tabs here. Probably gives us more flexibility in the future
as well. New function is serendipity.sync_heights() which takes no
args.

Also hide noscript controls for plugin manager differently, but show
them on no-js and touch devices. This is supposed to compensate the
fact that the dragdrop JS does not work on touch devices. Might need
a better solution long-term here.
Partial manual revert of 168cb146eaec3c568527bbc5dcf06b4cb6e9bda8.
Please note that this does *not* contain any changes to the UI as
discussed; those will follow later.
