v1.36 for MC 1.7 and 1.8

• Changed: the shopkeeper data now gets saved to file in a separate thread, hopefully reducing load on the main thread if your save file is very (very very) large.
  

Also please take a look at the changelogs of the versions since v1.20 for all not yet fully documented changes!

• If the trade for a written book fails players can sometimes still open and read the book if they close the shop and click the temporary fake book in their inventory fast enough. There is not much I can do about this..
• Server crashes and improper shutdowns might cause living non-citizens shopkeeper entities to duplicate sometimes.
• The 'always-show-nameplates' setting is no longer working on MC 1.8.
