- Added own algorithm environment (looks just like a Figure)
  (please use [algo2e] option for the algorithm2e package)

- The words 'thesis' and 'dissertation' were exchanged to their
appropriate meanings when using the 'english' option. (Thesis for
a Master's degree and dissertation for a Ph.D.) The command name
is still the same though: use \tese for a Ph.D. dissertation and
\dissertacao for a Master's thesis.
