Mega patch to improve how build dependencies are handled and

how packages are found.

First: I removed all these *-deps.db files and only a single file
is used now "build-depends.db"; it's smaller and will be easier
to handle in the future... when "run-depends.db" is added :-)

Second: there's no need to specify version of package anymore;
before you had to do:

	$ pkgfs.sh install git-1.6.0.2

now you only do:

	$ pkgfs.sh install git

This will read the variables located at PKGFS_TEMPLATESDIR/git.tmpl
and will the install the version that is there.

+ Glitz is a portable 2D graphics library that uses OpenGL to render hardware
+ accelerated graphics. It supports many of the latest OpenGL features, such as
+ efficient off-screen rendering using pbuffers. Rendering can be carried out by
+ arbitrary OpenGL layers, thanks to glitz's extensible backend system.
+
+ Glitz is designed to match the X Render Extension semantics and provides
+ a general way for accelerating this imaging model. Glitz can be used as
+ a stand-alone layer above OpenGL but is also designed to act as a backend for
+ cairo, providing it with OpenGL accelerated output."
