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.

+ GIT is a \"directory content manager\" designed to handle absolutely massive
+ projects with speed and efficiency, and the release of the 2.6.12 (and later)
+ versions of the Linux kernel as well as more and more other projects switching
+ to it would indicate that it does this task well.
+
+ GIT falls in the category of distributed version control software, similar
+ to e.g. GNU Arch or Monotone (or, in the commercial world, BitKeeper). Every
+ GIT working directory is a full-fledged repository with full revision tracking
+ capabilities, not dependent on network access to a central server."
