Quick bug fix for an incorrectly set value.

Fixed a couple minor issues with the 'Extreme' explosion mode.

Added an 'Extreme' explosion mode, which uses a workaround to boost the max explosion size by quite a bit. Not for potato computers.

Made the fire spawning mode far more effective, and made the explosive mode a slightly randomized explosion size for further intrigue.

Replaced the numbered particle styles with text descriptions of each particle style.

Removed 'omnidirectional' mode, instead moving it to the 'none' option under 'velocity'. Also added particle life options.

Added more particle styles.

Cleaned up UI, changed 'omni' label to 'omnidirectional' for clarity.

Added a handful of additional smoke color modes.

Added an animated 'blink' to the gun upon mouse click, and added a 'spawn fire' option alongside the 'spawn explosion' option already extant.
