Let version print partial matches for plugin name. Addresses BUKKIT-2383

If no plugin is found with the given name, the version command will
search all loaded plugins to find a case insensitive partial match for
the specified name and print to the sender all matches.
Clarify some of the verbose in SimplePluginManager.

When an exception occurs, the version of the plugin is not included.
Having this information would be beneficial to plugin authors performing
debug.

The list of authors for NagAuthorException verbose (although unused)
would be more appropriate to simply include all authors, as opposed to
the first appearing.
Add simpler API for using the scheduler. Adds BUKKIT-836

The new methods return the actual task that gets created from the
scheduler. They are also named such that auto-complete puts the
asynchronous methods after the normal ones. These two additions are
simply semantic.

Tasks now have a method to cancel themselves using their task id. This
is provided as a convenience.

A new class called SimpleRunnable was added. It is an abstract Runnable
such that anonymous classes may subclass it. It provides six convenience
methods for scheduling as appropriate. It also provides a cancel method
for convenience. The functionality of SimpleRunnable only stores an
integer representing the task id. A SimpleRunnable can only be scheduled
once; attempting to reschedule results in IllegalStateException.
Deprecate PlayerPreLoginEvent. Addresses BUKKIT-2600

PlayerPreLoginEvent was originally implemented with the intention that
putting synchronized blocks on the plugin manager made it thread safe.
Unintentionally, this causes the event to be executed when a plugin
would otherwise expect no events to be firing. It is now deprecated.
Add tab-completion API. Fixes BUKKIT-2181. Adds BUKKIT-2602

CommandMap contains a method that will auto-complete commands
appropriately. Before the first space, it searches for commands of which
the sender has permission. After the first space, it delegates to the
individual command.

Vanilla commands contain implementations to mimic vanilla
implementation. Exception would be give, that allows for name matching;
a feature we already allowed as part of the command is now supported for
auto-complete as well.

Plugin commands can get a tab completer set to delegate the completion
for. If no tab completer is set, it can check the executor to see if it
implements the tab completion interface. It will also attempt to chain
calls if null gets returned from these interfaces. Plugins also
implement the new TabCompleter interface, to add ease-of-use for plugin
developers, similar to the onCommand() method.

The default command implementation simply searches for player names.

To help facilitate command completion, a utility class was added with
two functions. One checks two strings, to see if the specified string
starts with (ignoring case) the second. The other method uses the first
to selectively copy elements from one collection to another.
Add a tab completion API for chat messages. Adds BUKKIT-2607

This implementation provides access to a (mutable) list and the base
message. Also provided is a convenience method for getting the last
'token' in the provided string.
Updated version to 1.3.2-R2.0 in pom.xml for RB.
Updated version to 1.3.2-R2.1-SNAPSHOT for development towards next release.
Override toString() method in Command

Overriding the toString() method provides more human-readable feedback
when a problem occurs, including the version of the plugin if
applicable.
Updated version to 1.3.2-R3.0 in pom.xml for RB.
Update Bukkit for Minecraft 1.4(.2) changes.
