Removed:

.bash_aliases

.bash_functions

* Both of these files have been replaced (by .aliases and .functions
  respectively)

New:

install.sh

* Script for installing dotfiles when the repository is cloned.
  Currently fairly rudimentary.  Inspired by (though code not taken
  from) Wesley Werner's script `bootstrap.sh`:

https://github.com/wesleywerner/dotfiles/blob/master/bootstrap.sh
Moved lots of files around: put stuff in links to be installed when
./install.sh is run.

Deleted a few out-of-date and no-longer-maintained files. .ps1 has
been superseded by .bash_prompt; .xsession by .xinitrc.

readme.md has been entirely rewritten to give a better overview of
what is currently in this repo.
Deleted .pentadactyl files which weren't actually configuration files.
Likewise for .xmonad files.  Also deleted out of date xmonad
configuration files. Renamed my nao config file. Deleted some no
longer used conky configurations.
