Widgets

[Caellian]

@rubyFeedback suggested addition of widgets in an issue some time ago. I'm closing that issue in favor of this discussion.

Basically, widgets can be almost fully emulated from Lua side already. I'd like to see suggestions with regards to how the community would like their API to look like. It might be nice to create a separate Lua library on top of conky for handling them, but conky could introduce some hooks to make the process of widget creation much nicer.

• This would have the benefit of making it easier to author widgets with less glue code as conky would pass events and call their render hooks directly.

Widgets could also make use of keyboard events.
