Fix up legacy code to use new interfaces

This took way more time than it was worth. Converted line endings to Unix, some other trivial crap. Thanks to Phoenix616 for already having a multi-version pom, it would have taken me much longer to figure out without a functional example. The only legacy code which is not supported is that of the pre-versioned package era. I compiled a copy of Craftbukkit about 15 commits prior to the introduction of versioned packages, and NMS had already been fiddled with. Anyone who needs support for builds in that range can use an older OpenInv build instead, it's not like UUIDs are a big concern.
Actually allow for offhand modification, whoops.

-## About
-OpenInv is a [Bukkit plugin](https://dev.bukkit.org/projects/openinv) which allows users to open and edit anyone's inventory or ender chest - online or not!
+## Goals
+This fork of OpenInv was created when the lag caused by offline player lookups post-UUID migration became too much to bear. Overall, it does not differ much from the original.

-## Features
- **OpenInv**: Open anyone's inventory, even if they're offline.
-  - Read-only mode! Don't grant edit permission.
-  - Cross-world support! Allow access only from the same world.
-  - No duplicate slots! Only armor is accessible when opening self (if allowed at all)!
-  - Drop items as the player! Place items in the dropper slot in the bottom right. Can be disabled via permission!
-  - Allow any item in armor slots! Configurable via permission.
- **OpenEnder**: Open anyone's ender chest, even if they're offline.
-  - Allow access only to own ender chest! Don't grant permission to open others.
-  - Read-only mode! Don't grant edit permission.
-  - Cross-world support! Allow access only from the same world.
- **SilentContainer**: Open containers without displaying an animation or making sound.
- **AnyContainer**: Open containers, even if blocked by ocelots or blocks.
+### Changes of Note
+- Removed updater
+- Removed wand

-## Commands
-See [the wiki](https://github.com/Jikoo/OpenInv/wiki/Commands).
+## Previous Versions
+Any version of Minecraft this fork has been existent for should have a [release](https://github.com/Jikoo/OpenInv/releases) tagged. Features are not backported, however.

-## Permissions
-See [the wiki](https://github.com/Jikoo/OpenInv/wiki/Permissions)

Jikoo	fb48f6a783	Fix up legacy code to use new interfaces This took way more time than it was worth. Converted line endings to Unix, some other trivial crap. Thanks to Phoenix616 for already having a multi-version pom, it would have taken me much longer to figure out without a functional example. The only legacy code which is not supported is that of the pre-versioned package era. I compiled a copy of Craftbukkit about 15 commits prior to the introduction of versioned packages, and NMS had already been fiddled with. Anyone who needs support for builds in that range can use an older OpenInv build instead, it's not like UUIDs are a big concern.	2016-03-04 05:49:07 -05:00
Jikoo	d761b6bfe4	Actually allow for offhand modification, whoops.	2016-03-04 00:53:21 -05:00
Jikoo	5b3ba79b82	Maven, huge refactor, interface changes Among other things, these interface changes allow for supporting pre-UUID Minecraft versions again. I may eventually backport older versions, but I don't know that I'll be able to lay hands on old enough jars. Removed static access Renamed all methods to follow conventions	2016-03-03 23:33:54 -05:00
Jikoo	3549431fbc	Removed item wand functionality Anyone who can use it has to be able to run the command anyway. If they can run the command, they can use tab completion to automatically fill in anyone online's name. There's no need to keep around a bunch of deprecated code for a function I sincerely doubt anyone actually uses.	2016-03-01 12:30:12 -05:00
