Subject: One function for producing Atom entry for a Notice
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=3ef4f251acbe8ebdfd9d7f1ea43b7344b7332b73;p=quix0rs-gnu-social.git

One function for producing Atom entry for a Notice

Took the various places that we create an atom entry for a notice, and
jammed them together into one function of the notice class, and then
used that function. Also, added Atom threading extension and
categories for hashtags.
