Users who want a user-specific bin directory to override system paths should
configure that in their user-specific ~/.bashrc, not in the system-wide init
file. The global file shouldn't add directories from user homes to $PATH
without knowing whether those actually exist or whether the users even want
them in $PATH. On my system, for example, there is no ~/bin, so I don't want my
$PATH to look for one. Removing an erroneous entry from $PATH is cumbersome,
but adding one is easy, so it feels better to err on the side of caution.

* Moved bash-specific code from /etc/profile to /etc/bashrc.
* Moved general Bourne shell code from /etc/bashrc to /etc/profile.
* Added "include guards" to both files to ensure that they aren't sourced
multiple times (which would result in lots of redundancy in $PATH, etc.).
* Both files include each other to make sure that the correct system
environment is always defined.
* When the current user has installed the 'bash-completion' package in her
$HOME/.nix-profile, programmable completion is automatically enabled in
interactive shells.
* The /etc/skel/.bashrc we installed has been dropped because it is redundant.
