* Make mac/win lookups lowercase'd
* Revert #709 & 81042cc
* Adjust HashPolicy implementation across sourcemod
Basically, in order to implement our own (actual) hash policy in
`PluginSys.h`, we needed to remove the blanket implementation of `hash`
that was used before. Now, each policy must implement `hash` along with
`matches` in order to be used with `NameHashSet`. While this does force
us to change every implementation of policies across the entirety of
sourcemod, it allows core to use flexible implementations of `hash`.
* Remove logic duplication
* Improve lowercase checks
In other words it was a problem where our FireEvent hooks were being re-entered for the _same_ game event. The Event Manager was not able to handle this and crashed.
Various minor things done to project files
Updated sample extension project file and updated makefile to the new unified version (more changes likely on the way)
Updated regex project file and makefile
