Multiple Tag Selection

[craig-s]

It would be nice if you could select multiple tags in the Navigation Drawer, so that filtering can be carried out with greater accuracy. The filtering should work in a way that, where multiple tags are selected, the included notes include ALL the tags selected.

It'd be really good while you're looking at this to get full boolean support for tag selection - so you could get one and the other, but not some other one, or yet another..
