Changed makefile to use -std=c++0x. Also changed a compatibility issue in game.h
Changed RNG to use STD's <random>, with std::default_random_engine.
The RNG functions now use uniform int distribution and uniform real distribution.
RNG namespace made. Only has normal function and the generator "gen".
Gen is seeded in main, directly after "seed = time(0)".
Revert "RNG namespace made. Only has normal function and the generator "gen"."

Ignoring unwanted files
Added sling and slingshot ranged beginner weapons

Atlatl not included. Sling levels up throwing, Slingshot levels archery.
Removed an unneccesary comment and a leftover ammo type
Add make target to cleanup test build artifacts.
Adjusted slingshot, added ball bearing ammunition

Sling and Slingshot should be completely cleaned up.
Fix color typo and remove redundant color in item factory
Move most of the generic items to JSON

Only handled things that used the MELEE macro and had no flags.
Let guns be defined from JSON as well
Merge branch 'master' into json-guns
Add no-arg it_gun constructor, fix a couple silly compile errors
Move skill initialization to happen inside the game's init method
Couple more item factory fixes
Merge branch 'master' into json-guns
Move all gun definitions to JSON

Also added a "range" field to the gun definitions, since I was touching them all anyway. Currently set to 0 for all guns, and unused, but lays the groundwork for making arrow range be mostly determined by the bow rather than the arrow.
