Start project "central login file"

The plan is to merge all login files into one file.
Merging different .profile files into main .profile
merge setenv.sh into new-profile
remove remote.profile, the code is present in the function host_math
merge new-profile and profile into one
update function names to be unset at EOF
merge envrc into profile
remove envrc
move functions to seperated files
change folding in shorter aliases file
add TODO item
move code to zshrc and remove bashrc
Merge branch 'profile'
Merge branch 'aliases'
add timezone info for Simone
fix bug with $PATH
add launchd commandline option (incomplete)

Try to modify the environment inside launchd to propagate it to all newly
started programms.  This is unfinished.
source .profile from .zshrc

This will set up the environment correctly until the environment is correctly
set with launchd.
Merge branch 'parallel-master'
Merge branch 'launchd'

Conflicts:
