2.6.8

A preset someone shared with you finishes

Opening a shared preset file installed everything in it, wrote it to your library, and then
stopped one line short of switching the mods on. Nothing said so: the window went on waiting for
an answer that had already failed. The same file split that broke Install in 2.6.5 broke this,
in the same way, and nobody had reported it because reaching it needs a preset file from another
player.

An action that fails says so

Any failure in the process behind the window used to leave the button it belongs to stuck on
"Installing...", with the reason written only to a log file. That is how a plain error looked
like a hang for two releases. The button now comes back and the reason is on screen.
