Release 0.15.2

Another bug fix release without API or ABI changes, mainly to
fix more known 0.15.0 and 0.15.1 regressions. But as a bonus,
it is now possible to build the DirectWrite system font provider
for Microsoft's Universal Windows Platform (UWP).

Two known minor 0.15.x DirectWrite system font regressions remain:

* when a font is attached/memory-loaded but a different (non-attached)
  style of the same font is used by the subtitles
 (only the attached style[s] will be used;
  this also affects Core Text since 0.13.0 but not Fontconfig);

* in the unlikely case that the full name of a system font
  equals the _family_ name of another system font
 (only the family name matches will be found).

Also please note that our IRC channel #libass has moved from freenode.net
to Libera.Chat, and all presence on freenode.net has been fully retired.
