Psyringe - added quantifiable target restrictions. Whenever you use square brackets [] to specify attributes of a target, you can use the operators <=, >= and = to specify quantities for power, toughness, and/or converted manacost. See added cards for examples.

Limitations:
- Operators for "greater than", "less than", "unequal" have not been implemented, but if a card actually needs them, you can use a preceding minus sign to negate a comparison. Example: -power=3 means "power not equal to 3", -toughness<=3 means "toughness>3".
- You can't use spaces when specifying such restrictions. Write "power<=3" instead of "power <= 3"
- You now need to use a space before the "<" and ">" commands that count the matches for lord(), foreach(), all() and aslongas(). So far we always did use spaces in front of them without actually needing to, now we need to.
- manacost restrictions don't take "X" costs into account. Example: Mistmeadow Skulkin (FUT) has protection from manacost>=3. Blaze has a converted manacost of 1, but when you cast it with an X of 2, then it actually has a converted manacost of 3 while on the stack, and Mistmeadow Skulkin would be protected from it, but currently it isn't.

Please review the code, I'll add a few remarks/questions of my own.
