style(app,method declarations): change way to declare methods
refactor: change title of index page
chore(shareMode): add indent to code
feat(share2): add share2 page

This page is supposed to be the same as share page, but with code
responsible for "Session" part of library being in different file.
For now, Session code is in different file and properly loaded by
"client" side js code, although there is no functionality that was
provided with share page.
chore(Gruntfile): look for jade files in subfolders as well
fix(shareMode,shareMode2): separate index page and share mode

While moving share mode to different page, forgot to change this
reference. Now it is fixed and share mode works on /share and /share2
pages
fix(session): let socket.io deal with connectivity to server

We just pass host written by user to socket.io and let socket.io deal
with all errors
