Substitute actual groups for the '%GROUPS%' placeholder.

I am getting rid of the dynamically-generated PKGBUILD system. It didn't
work quite as well as I thought it would.
Substitute package description for '%PKGDESC%'.

See commit 2cddc4353616992b6.
Substitute upstream package names for %PKGNAME% placeholders.

See commit 2cddc4353616992b6.
Fix 'sqlmap' pkgdesc.

It was missing for some reason.
Add 'jd' to 'other' possibility list.
Add a 'new-packages' directory with packages that need to be tested.
Update the 'template-making' scripts.

This updates the scripts for the template format that existed right
before I got rid of the templates entirely. This also does some general
cleaning.
Rename 'PKGBUILD.in' files to 'PKGBUILD'.

These files are now functional PKGBUILD files. The dynamically-generated
PKGBUILD system wasn't working quite as well as I expected it to work.

The new PKGBUILD files are optimized for the archtrack package
repository. AUR PKGBUILD files will be generated from these.
Make the 'make-info' script prompt the user for package groups.
Add package--<group list to the 'list' script.

The package--group list has been renamed to 'straight-associations'.
