DynamicMacros for PvP

Enhancement of addon logic in a way that instead of first occurence all character names on first line will be replaced with healer name and all occurences on second line will be replaced with damager name. This update should not affect your macros and all of them should still work without any modifications.

This feature allows creation of macros such this:

#showtooltip
/cast [nomod,@dynamicMacros]

/cast [known:Blessing of sanctuary, @dynamicMacros] Blessing of sanctuary; [@dynamicMacros] Blessing of spellwarding;

where first line with string @dynamicMacros will have all occurences of @dynamicMacros replaced with healer name and second line with string @dynamicMacros will have all occurences replaced with damager name.

Bug fixes.

WARNING:  Since those changes completely reworked code for evaluation which strings should be replaced feel free to downgrade to lower version of addon in case you run into troubles and inform me about bugs you find.
