Bug#1064456: libenchant-2: New upstream location, new version 2.8.2

[Philipp Matthias Hahn]

Dear fellow DD,

looks like "enchant" is no longer maintained upstream by "AbiWord", but
maintainership was transferred to "Reuben Thomas" and now lives at
<https://github.com/rrthomas/enchant/> respective
<https://rrthomas.github.io/enchant/>.

I tried to find some "proof" of official maintainership transfer, but so
far did not find any proof. "abisource.com" looks dead. The only hint I
found is that <https://github.com/AbiWord/enchant> now redirects to
<https://github.com/rrthomas/enchant>.

There also are new releases at
<https://github.com/rrthomas/enchant/releases>, current is v2.8.2.
