Generate tags more quickly by skipping crap I don't want
More permanently store helpful macros

Macros (and all registers, really) are captured in ~/.viminfo to persist

long time, but I'd rather they be permanent, always populating on each
computer I use, by generating them in my .vimrc.
Use a silent `curl`, but stop silencing errors
