Added process name/namespace option for compiling to client

[magnuspaaske]

Added 2 options for compiling to client JS with gulp-pug, namespace and processName. The namespace option creates a namespace so that all templates are compiled into the same namespace and can be easily found in the frontend code (as opposed to having all the templates being named 'template'). This change brings the processName option in line with grunt-contrib-pug (apart from a few details allowing this behaviour to only show up when the namespace option is set)

Hey @magnuspaaske, if you could provide some tests for this feature you are proposing, that would be nice.

(P.S. I don't use Pug much anymore, so let me know if you want access to maintain this better. 😄)

Hi @jamen
I'll add some tests – I assume 2-3 tests should cover the functionality we're seeking here.
As for maintain access, let's discuss that in a separate thread :)
