Adds the ability to set and environment variable RVL_SERVER to specify the floating license server (instead of searching for a settings file on disk) when retrieving floating licenses.

Some modes in Toxik could show a render failure message at the first and/or last frame of a sequence.

Fixed bug in FrameAverage where the plgin could return wrong results with Threashold set below 100% for images with transparent areas.
Fusion: Fixed an issue that made plugin really long time to initially load.
Nuke: Fixed a bug where DE:Noise retuned the first valid frame of a sequence for all frames before the first frame... fixed to now return a transparent frame where there is no valid source frames in the input sequence. Now properly supports AutoAdjust Mode in FrameAverage Plugin.
Toxik: Fixed a bug that could make Toxik crash.
August 29: fixed a bug in 64-bit Linux version where node-locked licenses were not properly seen.

Fixes a problem where Motion Weighted Average could cause the plugin to crash.
Fixes a problem in Toxik and Fusion where DE:Noise did not work properly with frame times less than 0 (usually in conjunction with a time offset tool preceding DE:Noise).
Fixes a bug with Smarter Blur when alpha is not full on at every pixel.
Fixes a bug with DE:Noise Frame Average when working on images that did not have full-on alpha at every pixel.

Fixes a compositing error in mode "Smarter Blur".
Fixed min/max/median and "best 2" functions when not full alpha.
Some non-full alpha cases calculate faster than version 1.0
Fixes a bug where DE:Noise could produce black frames when the temporal threshold was real small and the Temporal Process Mode was set to None.
Fixes a bug where a Temporal Process Mode setting of Median could occasionally return the wrong pixel.
FrameAverage tool: A bug was fixed where frames requested undertime 0 were miscalculated in some hosts (such as Toxik).
