* Make findcalibre actually useful By setting SEARCH_LIBRARY_PATH when a Calibre tree is found, so that book paths can properly be constructed. Users should still very much set it themselves, but at least everything works as intended when not, instead of mysteriously half-breaking later. Drop the SetDefaults bits, it appeared to have been added to fix no-ops detected by Luacheck, and it's actually non-functional, because SetDefaults doesn't handle saving variables it did not itself assign. So this was just causing the "Do you want to save new defaults" popup to show up on exit, but it couldn't actually do anything useful (like, say, save the new SEARCH_LIBRARY_PATH value). fix #4082 * Better comments about the state of NaturalLight on the Clara, and how this might translate to the H2O²r2. re #4015 * Make ScrolltextWidget refresh as "partial" only on actual Scroll events Moving the cursor should stay "ui", or things gets annoying really fast ;). re #4084 * Bump base to pickup ZMQ fixes (fix #4086)
