Bug 1057231 patch 3 - Add new cascade level for rules from SMIL Animation of SVG attributes to the style set. r=dholbert

Browse Source 
I will fix the indentation of gCascadeLevels in bug 977991 patch 2,
which adds a member to each element of the array.

Note that this bumps the maximum sheetType from 8 to 9 (and number of
them from 9 to 10), which does not require updating
NS_RULE_NODE_LEVEL_MASK, since NS_RULE_NODE_LEVEL_MASK currently has 4
bits and allows a maximum of 15.
