Bugfix for Infinite Trading

This should fix a bug that happens when using the mod together with the Infinite Trading mod (Serilum/.issue-tracker#99)

First version that works with Rift

This is my first attempt at porting the mod to 1.13.2, using Rift instead of Forge.

It needs my own version of Rift that already includes some code that I sent as a patch request to Chocohead - download from https://github.com/gbl/Rift/releases/tag/SNAPSHOT-1.0.4.77.

1.2

New markers for trades - green arrows for open trades, white arrows for trades that the villager accepts but you don't have the items for, red stop signs for trades that are locked.

Also, there are 1.12, 1.11.2 and 1.10.2 versions now. The 1.12 version works with 1.12.1 and 1.12.2 as well.

1.12 compatibility

Build of version 1.10 against forge 1.12-14.21.0.2335. Minor modifications to the config code that are required by 1.12, but shouldn't be visible to the user.

Just Enough Items compatibility

This version adds a config option to display the trades list left of the standard GUI. The option gets set automatically if Just Enough Items (JEI) is loaded when starting this mod for the first time, and can be changed any time in Mod Config.

1.01

Various bugfixes and improvements:

• long trades lists center-align with the original gui now instead of top; this helps shepherds especially with their long list of different coloured wool
• fixed display of items like pumpkins and melons that were shown too dark
• several additional null pointer checks to prevent crashes
• code cleanup
• removed most debugging output
• better check if two itemstacks can be merged, this prevents trade results being put into the wrong locations resulting in items in the hand after trading
• added link to mod URL
