The ContextualMenu now accepts a zIndex parameter which can be used to control its level. Dialogs are at around 4000 in the z-index, and the context menu defaults to 5000 for the things that need tooltips and such in a dialog.
Also fairly significant refactor of the uploading code: there are
a number of different ways of triggerring a file upload and each
went through a different code path (the media config size limit
worked on one of those paths). Basically take a lot of code out
of the views and put it into ContentMessages.
Sorry about the size of this patch.

The `Notifier` class expects push rules to be available, so it can explode in
strange ways if called too early. This changes to wait until the sync is in the
`PREPARED` state (when push rules should be ready) before using the `Notifier`.

This turned out to be much more complicated than it needed to be. We use an IndicatorScrollbar to do all the math for us and some minor changes have been made so it can flag left/right overflow. The complicated part is the css changes which make the gradients work: unlike the RoomSubList, we have to calculate the offset of the indicators (gradients) on our own because position:sticky doesn't work horizontally.
The changes to the css (well, mostly pointer-events:none) make it so the gradient doesn't interfere with the room avatars.
9034 and 8954 are fixed by this because they represent an overflow-x:none style breakage where browsers won't let you scroll without a scrollbar. The gradient offset problem is also demonstrated in 8954.
This changes errors that may occur when loading the room directory so that the
message appears inline with the overall directory UI instead of in a new modal.
This is important so that the new room button remains on screen even if the
directory is down.

componentDidUpdate is called a lot, and we don't really want to keep checking the messagePanel, so this introduces a new flag to check if the init is even needed.
