Subject: [PATCH] Added glPushMatrix/glPopMatrix-pair to LightningHandler.
 LightningHandler.onRenderWorldLast() modifies the model/view matrix and
 should therefore save and restore it. Actually, it introduces round-off
 errors into the model/view matrix by translating to world coordinates and
 back (calls to GL11.glTranslated()) which are proportional to the world
 coordinates' values (distant coordinates like 29 million introduce quite
 significant errors). Not restoring the matrix therefore makes it hard for
 other mods to do rendering correctly at distant coordinates.
