Updated to CB 1.4.6-R0.1 (This version only works with 1.4.6).
Added a configuration file (see the "Config" page for info on what each option changes).
Added PluginMetrics for tracking and sending plugin statistics to http://mcstats.org/plugin/SparkTrail/ (Opt out in the PluginMetrics folder if you do not wish to send information to MCStats.org).
Added the "death" effect - /spark death
Added the /spark player command for activating effects on other players with prevention for offline players and invalid effect arguments.
Fixed an internal error that results from an invalid or incorrectly spelt potion color when using /spark potion <color>.
Prevented usage of certain block effects that previously crashed the Minecraft client.
Slowed down the block break effect timer to reduce the lag produced by multiple players using the effect. This interval is configurable in the configuration file.
Changed the block id command to /spark blockid <string>. The types can now be found by using /spark list blockid.
Added the SparkMenu package - Use /sparkmenu to access an inventory interface for selecting effects.
Added the SparkBlock package for adding effects to blocks - Use /sparkblock for help on usage of the SparkBlock command or see the "SparkBlock" page. And no, I cannot add potion swirls for blocks as the effect uses Entity Metadata.
Added a wand (configurable in the config file - default '399') for SparkBlock - Right click on a block to check the activated effect and disable it.
Some bug fixes in the main package to do with effects and messages.
