FIX: force encoding for title field

Job exception: incompatible character encodings: UTF-8 and ASCII-8BIT
--
This exception rise up for correct(!) UTF-8 cyrillic (in my case, but non-latin overall, I suppose) in title field during RSS polling (feed polling url) and breaks topics creation.
So, just force_encoding() makes it work.

Fix buggy autocomplete behaviour for non-US keyboards

This change moves the code for actually entering data from the keydown handler to the
keypress handler, which can reliably catch the character entered (rather than
the key pressed).

This is my second attempt at
https://meta.discourse.org/t/typing-shows-on-non-us-keyboard-layouts/20449
without doing dangerous refactoring.

This does not fix the issue reported in
https://meta.discourse.org/t/overly-aggresive-emoji-autocomplete/20691/7
as that is a different bug.

FIX: honor `email_token_grace_period_hours` setting correctly

The documentation said that the unit for this setting is in *hours*, but the
code is treating it as *seconds*. Also, `Numeric#ago` has been deprecated since
Rails 4.1 (precisely to help prevent these kind of bugs) and will go away in
Rails 4.2.
