Subject: Improved fbgs

* Support almost all fbi options
* Add long versions of the options
* Add option -b to make optional the ringer when the document is ready
* Add option -r to render document with an arbitrary resolution
* Add the options -fp and -lp to view a limited range of pages
* Fix help text
