Implements helper functions for random number generation.
Implemented using C++11 <random> library.
Exported Lua Functions:
- seedRNG(seed)
- rollInt(min, max)
- rollDouble(min, max)
- rollNormal(mean, std_deviation)
- rollBool(chance_for_true)
- resetIndexRolls(string, array_length) --String identifies the instance of SimpleNumDistribution to reset
- rollIndex(string, array_length) --String identifies the instance of SimpleNumDistribution to use
--(Shuffles a vector of indices, Next() increments through then reshuffles when end() is reached)

Fixes plugin_init()
Misread the lines indicated by lethosor to be excluded, had broken the plugin in the process.

Cleans up cxxrandom.cpp
DFHack contributions specifies:
-spaces instead of tabs, so tabs were converted.
-C++ headers before dfhack stuff, so it was done
*Also added author name, creation date, and last updated date.

Updates cxxrandom, fixes instance leak
deleted header
moved definition to cpp file #lethosor
fixed singleton instance, no longer a pointer
commented out dfhack commands, now only init/shutdown and exported lua functions

Fixes RollIndex and Renames RollNormal
Renamed the Normal Distribution RNG function to fit the standard.
Now named RollNormal(m,s)
Fixed some wonky white space in the lua macro export block.
Fixed a stupid mistake with the RollIndex output. (it was outputting 0's)
Updated usage details.

Implements SimpleNumDistribution
Exported additional functions to lua.
Functions allow the generation of random 0-N index values.
Generation promises all unique values [0,N] will be returned once each when generation is run N times.

Implements cxxrandom
cxxrandom was implemented using a singleton.
This singleton provides an interface for generating uniform numbers, or numbers in a normal distribution, and also booleans(given the probability for the true outcome)
The singleton interface is wrapped in functions which are exposed for lua usage.
Integrated into plugins/CMakeLists.txt

The presence of syndrome data in unit.syndromes.active generates corresponding wound data in unit.body.wounds. This wound data acts to produce all of the syndrome's actual effects, including but not limited to flag changes, interaction abilities, body transformation and display name alterations. Wound data persists when syndrome data is cleared from unit.syndromes.active. Since syndrome-util did not touch wound data at all, the erase function was completely ineffective at actually removing syndromes.
Note that syndromes also generate a bunch of data in the historical figure information of units. I have observed that this historical data is sufficient to restore the syndrome in a unit following map reload (at least in adventure mode), so its clearance (which needs to also include any corresponding interaction effects) will have to be addressed in a future update. As is, syndrome erasure remains incomplete.
