shaderMeister V1.1c for 32- and 64-bit Windows

This is V1.1c of shaderMeister.

Changes since V1.1b:

• Fixed a crash bug when using the Surface Exposure Node

Changes since V1.1a:

Changes since V1.1:

• Fixes to the preset system to make it more tolerant to directories and files others than presets in the preset directory.
• Added the ability to define custom locations for presets
• Made the warning when applying the shader more explicit.
• Fixed an issue with the master handler reading beyond the settings designated to the plugin within the LWS

Changes since V1.0:

• Added a LightGroup Node that affects upstream nodes connected to it.
• Add a node for a single, global LightGroup. This is saved with shaderMeister and can either affect upstream nodes as the normal LightGroup Node does, or can affect the shaderMeister shading graph if it is enabled in the master plugin.
• Various internal changes
• Minor bugfixes to the order of evaluation of the inputs
• Added a third party SDK, available upon request.

• The custom preset directories would not overwrite the default ones as described in the documentation
