[tlu] new beta

[Adam R. Maxwell]

Okay, yet another beta, which should work around the problem Bruno was having.

https://github.com/amaxwell/tlutility/releases/download/1.22b8/TeX.Live.Utility.app-1.22b8.tar.gz

Reminder: to test it, quit TLU and run

defaults write com.googlecode.mactlmgr.tlu TLMTexBinPathPreferenceKey /usr/texbin

A few other bugs are fixed too, like the total deletion of all mirrors in an earlier beta (apparently the Cambridge CTAN mirror is gone?), and breakage of the TeX Distribution selection on 10.11.

Additionally, you can change the documentation install preference (Configure menu); this allows BasicTeX users to install docs.
