Have CKAN generate a log of its installs/uninstalls/upgrades

[linuxgurugamer]

Sometimes, when I'm trying to figure out a problem, I delete a number of different mods, one at a time. When done, I try to reinstall them, but there isn't a session history that I can find.
Essentially, what I'm suggesting is to write the output which gets written to the "Installing mods" tab to a log file, possibly with a date/timestamp.

I'd also like to see some kind of historic record of mods installed/updated: Something's broken MechJeb's autowarp for me, but unfortunately, as I hit the "Mark all updated" button, ran the (numerous) changes, and then closed CKAN, I have no way of figuring out what might have broken it :(

This could dovetail nicely into #1155

Any work done on this? It would be very helpful!

Thanks to #1881, save this file alongside your ckan.exe and change WARN to INFO, and you get a nice enough CKAN.log file:

• https://github.com/KSP-CKAN/CKAN/blob/master/GUI/log4net.xml

However, it could be easier to read (just installs/upgrades/removes and other things the user cares about) and easier to configure (without editing XML). Leaving this open for that.
