- add multi_mask, negative_mask, and multi_strength
+ some keywords may describe multiple cipher suite parameters at once
- fix masks decision tree
+ all masks have to fit the cipher suite to include it
- correct 'action' evaluation
+ plus sign means ordering (which NSS does not support)
+ no sign presence means adding implicitly
- extend keywords for new future ciphers
