Start renaming MKAYSIGREP to MIKAELA_GREP

TODO: shell-things function & grep for MKAYSI & maybe check the install
scripts once again.
bashrc & gpg.conf & zshrc: remove more MKAYSI
.files: continue replacing MKAYSIGREP
bashrc & zshrc: fix MIKAELA_GREP file
bye MKAYSIGREP

TODO: fix shell-things to also check for ancient MKAYSIGREP files
.install.MIKAELA_GREP.run: don't perform duplic...

...ate commands with install.run!
install.run: detect MIKAELA_GREP and run it
bashrc & zshrc: remove MIKAELA_GREP from sh...

ell-things fuction, it's ran by normal install.
install.run: remove wwwuser

that hasn't existed in a long time, but is still here?
install.run: fix yet another MKAYSIGREP
*install*.run: setting and unsetting x
install.run: move ifs to the end
install.run: don't hide output of chmod
chmod: set +x in the end
gitconfig: add pullen alias

same as pulln, I just feel like it should be there.
Merge branch 'mikaela'

good bye MKAYSIGREP
