[aur-general] package review and merge request

[Jeremy Audet]

User "Trbs" from the mailing list replied [1] promptly. He stated that the
shebangs should not exist and suggested I create a patch to remove them
entirely. (He also removed the shebangs from the official repo.)

Thanks for the sample code, Doug and carstene1ns. I used it as the basis
for a prepare() function that removes shebangs. I tested the package [2] on
a python 2 django project I have handy. In particular, I made sure to
exercise the dumpscript.py and pipchecker.py scripts. No problems.
