Added LaTeX temp files to .gitignore, + minor cleanups

  * removed textcase.sty from Makefile USEFUL_PACKAGES
    I'd tried it out on the hyperref/uppercase problem,
    but it didn't help, so we don't use it anymore.
  * add \foorloop usage information to blabla.
  * alphebetized draftmark's dependency listing.

Merged Evan Sultanik's December 2009 multiple-advisor drexelthesis.cls.

Changes vs. Evan's implementation
  * use \expandafter to avoid involving \@mainaux
  * use already-defined \alph{} rather roll-your-own \@alphabet
  * many advisors case printed "A, B, and C" rather than "A, B and C".

Unrelated changes
  * \@advisor -> \@degree typo fix.
  * \@sect and \@ssect pseudocode now in |example| environment.
  * natbib's unsrt analog is unsrtnat, not plainnat.

Finally, I packaged the whole thing into \@advisor, so the compositing
logic can be used in multiple places

Added blabla.sty to Makefile clean

Added example PDFs to the Makefile too

Oops, add drexel-logo.pdf to EXAMPLE_FILES in Makefile

Major reorganization.  Vast improvements.

 * incorperated documentation from the base .dtx files.
 * improved hyperref and natbib integration.
 * cleaned examples.

Better handling of figure/table/caption spacing.

Added \@dsp for flexible control of display (equations, etc.) spacing.

Removed \DescribeMacros call, since its not defined :p.

Defined \blabla for creating a dummy text in bulk, and added calls to
the examples.

Broke \set@lines@length out of \blanklines

Added draftwatermark handling, graphicx explanation.

Actually, the CS class seems to have tried to use _both_
  a draftcopy implementation (in \DeclareOption{draft})
_and_
  a handrolled \AddToShipoutPicture implementation
  (in \DeclareOption{draftwatermark},
   called by \DeclareOption{draft}).
I imagine this was due to inter-developer miscommunication...

Anyhow, I like draftmark ;).

annotate isn't what I'd thought it was.  Remove it for now

Fix \makecopyrightCC implementation

"\vfil" -> "\vspace*{\fill}" (better LaTeX idiom)

Add \m@kecopyright + swap \listof* definitions

Began importing option descriptions from drexelthesis.cls
  http://www.cs.drexel.edu/~jeffa/talks/drexelthesis.cls

\newpage -> \clearpage

According to
  http://help-csli.stanford.edu/tex/latex-pagebreaks.shtml
\clearpage is similar to \newpage but figures are also printed.

So there is no situation in our class for which we would prefer
\newpage over \clearpage.

Fix "*" -> "def*" in \defmonth/\defyear example

Began versioning
