This just adds a bit of information to the AsyncTabSwitcher's
logging and cleans up the display to make it quicker to find
what changed, especially with large numbers of tabs. The bit of
new information that I'm particularly interested in is what
event triggered a particular update - so now every time we call
postActions, we include the name of the event.

We maintain a simple LRU cache of tab layers by setting their
docShellIsActive = false with preserveLayers(true). Once they
are pushed out of the cache by more recently used tabs, their
layers are discarded.
Luckily most of the complexity of this could be contained in
the AsyncTabSwitcher - the one change that had to sit outside of
that was moving the aTab.closing = true earlier in the removeTab
call, so that we could use that information to eagerly evict tabs
from the cache. This was to address a leak in a few tests on try.
