Various clean up (#134)

* Fix reference and grammar

* Remove obsolete package

* Use colored links in pdf, black when printed

We can debate the colors to use of course, I left the defaults in.
There are accessibility concerns with colors...

* Add supporter.csv to the list of TeX source

So we rebuild everytime we add a new supporter.

* Inline the list of supporters

Those guys are awesome, but do they really need to be in a table one per
line over 3 pages?

* Explicit figure location

h rarelly works, so making it clear top is also an option.
