adding style for CC-derived modes

it looks it's quite powerful tool. I could even create separate styles
that I could change 'on-the-fly'!
fixing the recipe for mu4e a bit

I think 4.x branch is doing shell execution a bit differently
liking helm even more!

the only thing that I miss is the history of M-x calls; need to figure out
how to get it back
little improvements to SOCKS proxy preparation function
re-enabling more el-get packages

they started working again...
for some reason, helm-projectile is not autoloaded by default...

this should take care of that
