Added new Makefile.win, it only has dev/build/check targets

Add Makefile.win example
Add Chocolatey references + required packages

Gruntfile now appends .cmd extension to r.js if platform is win32

make -f Makefile.win to build on Windows

We now no longer need the step of pasting the json code into a standalong .js
file.

Also, moved locales.js to ./src folder.
Add it as dependency to utils.js and remove it from the deps scripts

instead of having to create a .js file with translations.

Polish translation of version 0.8.6.

Add fullname and jid to contact's tooltip in roster

It seems title attributes are limited to 512 chars, we will have
to live with that unless a custom tooltip is used.

Converse.js will now send chat state notifications of <paused>, <inactive> and
<gone> when the user has stopped typing for 30 seconds, 2 minutes and 10 minutes
respectively.

removes need to modify index.html all the time.
