fonts built with icomoon

https://github.com/jcbrand/converse.js/commit/47e00ae005fc4034836595d4267953b46a869cb7

- HAS_CSI might be called before features have been received. Instead, set a
  flag whenever a feature is received and check for that flag.
- Converse.ping was sending stanzas to the bare jid instead of to the domain.
- The handler that updates the date the last stanza was received must return
  true so that it gets called again.
- Only register the Pong handler if Ping is enabled.
- Rename lastMessage to lastStanzaDate to make it more clear.

Also use and add a Strophe namespace for CSI.

from version control because they bloat the repo, especially diffs of minified
files, which are large.

I was getting the following error while running make all on my windows machine
"""
node_modules/.bin/bower install
'node_modules' is not recognized as an internal or external command,
operable program or batch file.
make: *** [stamp-bower] Error 1
"""

This was resolved by adding the complete extension to the windows path.

In this case, it will force changing presence even if the user
specificly set another status.

Add functions for changing user presence to ``away`` or ``xa``
