(for 1.5)
This update is larger than it seems.
I reprogrammed the complete command handler. Because of that ARM supports custorm commands now. You can create an alias for the root command of arm in the commands.yml of you server. ARM will dedect it and replace the normal "/arm" root command with the one you selected on every error message and on the help page. You can also change the bad syntax message now.

The next feature is the first implementation that allows region reselling.
If you give your users the permissions they can resell their region to an user by creating an offer. Offers can be accepted and rejected. Offers will time out after a specific amount of time that you can select in the config.yml.
Offers will take care of the Limitations and permissions you've set for you users.

The last feature are the automated setup commands. You are now able add commands to presets. These commands will be executed if you create a region. You can also write variables in the command that will be replaced by the plugin. These are: %regionid%, %dimensions%, %regionkind%, %regionkinddisplay%, %world%, %price%, %extendpercick%, %maxrenttime%, %extend%

For example you could add the command "rg flag %regionid% use allow" to your preset. All regions you create now will have the worldguard flag "use: allow"

Moreover the help page is a bit clearer now. It's now sorted and has pages.

(New) Commands:
- /arm [sellpreset/rentpreset/contractpreset] addcommand [COMMAND]
- /arm [sellpreset/rentpreset/contractpreset] removecommand [ID]
- /arm offer [REGIONID] [PLAYER] [PRICE]
- /arm offer cancel
- /arm offer reject
- /arm offer accept

(New) Permissions:
- arm.member.offer.create
- arm.member.offer.answer
- arm.admin.preset.addcommand
- arm.admin.preset.removecommand
