Export KDE_SESSION_ID so that python-keyring detects KDE

It's an OpenSUSE oddity, apparently. It's fixed in the latest released version,
but that's not what is available in the repositories.

Also, purple-ize the sudo prompt, having it ask for the target user's name
password, instead of just the simple static "Your", which isn't portable across
different environments. Like, OpenSUSE, which defaults to asking the user for
root's password, not their own.
Fix the zsh syntax highlighting for dotfiles

Since I moved the directory for OpenSUSE, so I need to update the paths. Also,
I've long since fixed the erroneous spell check highlights in shell files so
no need to disable spell check in those files.
No need for the title() function when I have termtitle()

Old duplication of shell. Silly Young Colin.
ls when I change directories, and update the shell title

Now using add-zsh-hook! Woo.

Complete the deletion of tagbar

This is odd, but just go with the flow in git...I'll fix it later.
Ignore the private environment zsh.

Stick things like access keys, private data, or other sensitive but
troubling-to-type information in there. Better yet, stick it in an encrypted
wallet and ask KWallet for the information, but not many programs expect data
from an external command, in stead the environment, so here's a good place to
put it.
