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.

+ Python is an interpreted, interactive, object-oriented programming language
+ that combines remarkable power with very clear syntax. For an introduction
+ to programming in Python you are referred to the Python Tutorial. The Python
+ Library Reference documents built-in and standard types, constants, functions
+ and modules. Finally, the Python Reference Manual describes the syntax and
+ and semantics of the core language in (perhaps too) much detail.
+
+ Python's basic power can be extended with your own modules written in C or
+ C++. On most systems such modules may be dynamically loaded. Python is also
+ adaptable as an extension language for existing applications."
