New:

• Courier Letters can be put into ItemFrames - in effect creating posters/flyers (ticket #90)
  • One 'real' Minecraft map per Letter added to an ItemFrame will be used. This option is configurable (default: true) since many such Framed Letters in one small area might cause lag (untested).
• Blank Parchment can now be crafted for use when writing Letters, instead of just having the specified resources subtracted from inventory (ticket #17)
  • This is set to false by default since it's a major change, but most RP servers that use Courier should find this very appealing - I hope.
• Uses ItemMeta ('Lore') to show Letter info in inventory (ticket #89)
• Letter fees can be deposited into Bank or Player accounts (ticket #78)
• Config option to allow delivery in creative mode (default: true). See this forum thread)

Fixes:

• Letter text layout should make better use of available width.

There were some major changes under the hood in Courier for this release. I believe it's well tested but as always, backup before use.
