Feature Request: Item logs

[peov]

From Phil's Stream today.
Items are randomized and in the logs. They should be parseable and viewable in the tracker, i.e. to see if a failed run was doomed to begin with or that missing full restore was just 2 trainers away.

To me this looks like a twostep implementation:

1. build the log parsing (RandomizerLogParsing.lua)
2. add new Screen to log viewer UI for display of items
   2a. Implement base view
   2b. filtering per location (like pokemon on trainers)
   2c. filtering per item (like moves on trainers)

Would be willing to implement but am sort of a noob to lua, therefore forgive me stupid PR's

Yikes, just noticed that the randomizer does not log items. Gotta submit a PR there first. At least that is Java lol
