Optimize mapping rule properties to strings and engines

[danielkrupinski]

Before

• MATCH_PROP_STRINGS allocated heap memory
• RULE_ENGINES allocated heap memory
• Rule::allMatchPropStrings() allocated heap memory
• 3 copies of prop strings existed in memory - string literals in the binary file and 2 copies in the heap memory
• Linear search in Rule::matchPropFromString()

After

• No heap memory allocations
• Only 1 instance of prop strings in memory
• Binary search in Rule::matchPropFromString()
