Remove maid

Browse Source 
As much as maid was fun to write (and use!), having two separate files
for each of your dotfiles is a fundamentally flawed design. Using GNU
Stow for dotfiles is a much better way to get things done since the
files are linked: updating ~/.vimrc will automatically update the .vimrc
in your dotfiles directory, and vice versa.

Additionally, GNU Stow makes it easy to pick and choose the dotfiles
that you want to use. If you don't want to use a certain configuration
anymore, it's easy to "stow -D <config>" instead of having to manually
go into the .config directory and remove the offending files.

# Maid is a command line interface to handle the process of moving dotfiles from one
# location to another (i.e. between your local filesystem and the upstream repository)
# NOTE: For Maid to recognize the dotfiles you want, they must be in upstream first
# Use maid add <FULL_PATH> to add a dotfile to upstream (e.g. maid add ~/.vimrc)
# TODO: Use .maidrc to store configuration (?)
# If so, add Maid.init() to create a base configuration
