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.
