Various clean up (#134)

* Fix reference and grammar

* Remove obsolete package

* Use colored links in pdf, black when printed

* Add supporter.csv to the list of TeX source

* Inline the list of supporters

line over 3 pages?

* Explicit figure location

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