chore(release): start 1.2.6 taco-salsafication iteration
chore(travis): force the latest version of selenium

This might solve some flakiness on SL. At least Santi said that ;-)
docs: use q-io instead of deprecated q-fs

This recursive process.nextTick error[1] was probably coming from q-fs,
which is not actively maintained. This updates to q-io/fs instead.

chore: run docs unit test only once

Before we would run them twice on Travis. I don't think it should be part of ci-check task.
fix(jqLite): support unbind self within handler

If an event handler unbinds itself, the next event handler on the same
event and element doesn't get executed.

This works fine in jQuery, and since jqLite doesn't support .one, this
might be a common use case.
docs(ngIf): remove invalid comment from CSS

We cannot use valid /* ... */ CSS comments in examples because they break the parsing
of the ngdoc comments.  We can't use inline // comments because these are not valid in
CSS.

We could use the //!annotate extension to the ngdoc parser but this does not seem to be
working.  It is best to simply remove this line.

Closes #5234
docs(css): improve definition table style

Text in definition tables are now aligned to the top of the cell. These are used in
