Add termite configuration (base16 default dark colorscheme)
[zsh] don't force termcap
[zsh] removing unnecessary line from $path

In arch linux, path is generated from `/etc/profile`, which is loaded
from bash and in zsh through `/etc/zsh/zprofile`.
[zsh] add vte magic

For some reason beyond my understanding in Arch Linux files in
`/etc/profile.d` ran through a dumb terminal (or at least not an
interactive one), therefore `vte.sh` (part of the `vte3` package) aborts
soon, not allowing the functions like `__vte_osc7` to be defined.
[zsh] minor refactor
