This updates to 5.21. Just minor changes in this version, probably the most important of which is the first:
- Changed default text source from Twitter to Wikipedia, since Twitter now requires a login to get any feeds. - New version of fireworkx. - Minor fixes to distort, fontglide, xmatrix. - New MacOS crash in bsod. - New mode in lcdscrub. I tested it in Cauldron and verified that it works fine, including all of the screensavers mentioned above (except xmatrix which we have disabled).
