use bower.io to require the jstree?

[cordoval]

i am doing this in a project, perhaps we can do this here too?

we had the same discussion in symfony-cmf/create-bundle#45

one problem i see is introducing the requirement for yet another technology (nodejs) and another installed tool (bower). and having 2 ways of doing it, one in pure php, one with node+bower, is redundant and we risk that one of the two breaks without us noticing...

btw, #64 is upgrading to a new version of jstree. after that is merged, i am open for proposals how we could do things. maybe the right answer is to ask people to use bower and explain to download the js into app/Resources manually if they don't want bower.

2.0 will now use bower 🐦
