update jquery / allow to specify a jquery/framework

[Zauberfisch]

jquery should be updated (I recommend moving to 2.x since old browser support is not an issue in Firefox anyway.)

also, there should be a way to specify your own jquery.
an easy solution would be to allow to place a file ~/.js/jquery.js or lets put it more generic ~/.js/framework.js.

of course this raises the question why not just put it into ~/.js/default.js
but I see 2 good reasons:

• seperate framework from user code
• just putting my own jquery in default.js would mean double jquery inclusion in dotjs alone

also, it might be a good idea to check with the chrome plugin how they handle this to keep the behavior consistent

I wonder if it's even a good idea to always include jquery always anymore. I'll have to look at what the chrome version is doing.

well nowadays we have things like querySelector along with great native APIs, I dont think jQuery is required anymore

Besides we not using cross-browser, or heavy ajax scripts

It'd be nice to be able to either toggle the inclusion, or to add a preference field where you could specify a default library/framework to be included (multiple?).
