waiting until emojione:emojione becomes available

Keeping sync

RTL Support -  I just need to create the language selector now.

Integrated hubot

This is a work in progress of the RTL Support. It includes several
update to the input and textarea elements that aren't yet supported both
RTL and LRT writing (using `dir="auto"`).

This is a work in progress of Rocket.Chat RTL Support. The work is not
finished. I didn't know where to put the .rtl class in the html file, so
I use the addClass method in layout.coffee. Please write down suggestion
and don't accept this pull request yet, until final version.
