BlastFX 1.2.3 Released

Just a small update:

• +/- keys can be used to zoom
• Added two new examples, a bullet impact/spark and an explosion that uses subtractive blending
• Fixed the node graph load button being hidden behind the graph zoom input box
• Changed the general font so that the application can be used at smaller window sizes, not ideal, but still usable
• Added a new effect node 'Fix Alpha Edges' - this will correct the dark edges that can be seen on soft-edged particles
