2.0.0

What has changed?

• Added a new @Completer annotation that you can use to specify a custom tab completer for each command parameter.
• Changed package structure from me.vaperion.blade.command -> me.vaperion.blade.
• Added a new BladeArgument class, that now gets passed to the argument providers instead of just an input string. This change lets us check whether the argument was provided in the command, or it's a default value, so we can perform different actions on it (an example being the reserved null value).
• Added more documentation.
• Added defaultPermissionMessage to the blade builder, you can now specify a default message instead of having to configure it for each command separately (although you can still do this if you want a different message for some commands).
• Added a new section(String) method to the blade builder that you can use to change the fallback prefix for some commands if you want to use the same blade object for multiple plugins.
• The old default help generator was renamed to NoOpHelpGenerator and replaced with a basic generator that displays all the commands available to the command sender.
• Added a new setting to the @Optional annotation called ignoreFailedArgumentParse. When this is true, if the argument provider fails to parse this type it will pass null instead of showing the usage message to the sender (for example, if an invalid player is provided it will return null).
• Fixed: #3 #2 #12
