[aur-general] several requests

[Kevin Vesga]

 First lua5.2[1] from the AUR can be deleted since lua in Extra has been
updated.

Second there are two outdated packages: rsyslog-dev[2] and thinkhdaps[3]
that I would like orphaned. I have contacted the maintainers on Nov 20, but
they have neither updated the packages, orhpaned them, nor responded back.
