Update repository URI
Remove support for Suhosin.

The project seems to be dead with no commits over the last year.
Also, the latest version lacks support for the 5.4 & 5.5 branches.

Although direct support for Suhosin has been removed from phpfarm,
it can still be used by adding the appropriate code in a custom
options.sh to fetch and apply the patch manually.
Minor tweak.
Merge branch 'master' of github.com:fpoirotte/phpfarm
Simplifications in the code.
Only --enable-sqlite-utf8 on PHP <= 5.3.x.

Fixes #5.
Options can be made even more specific.

Allows options to be set for very specific versions of PHP,
eg. "5.5.4-32bits-debug-gcov-zts".
Improve the documentation.
Fix several styles in the doc.
Fix wording.
