Give users someone to complain to

Add myself as the maintainer of the dummy package.
Add comment of equivs upstream bug report
Be more careful about cd'ing into install-tl dir

There could be other directories or files that match the
glob install-tl*.
Add a progress update for install-tl (fixes #5)
Remove trailing spaces
Add option for a TeX Live profile (fixes #4)

A profile can be specified with the --profile option
of install-tl-ubuntu. This is passed on to install-tl.
An example.profile is included with the repository to
give users a starting point for creating a profile.

A few of the checks are disabled if a profile is used because
install-tl-ubuntu is not smart enough to adapt depending on
which components are selected for installation.  For example,
font configuration commands do not report errors.
