#3 Add dynamic variable query/set functions

[Grant McDorman]

In conjunction with the proposed extended script functions, functions to look for, query, and set local variables in scripts and objects should be added; specifically:
short xVariableExists <ref>, <string>
long xGetLongVariable <ref>, <string>
short xGetShortVariable <ref>, <string>
float xGetFloatVariable <ref>, <string>
xSetLongVariable <ref>, <string>, <long>
xSetShortVariable <ref>, <string>, <short>
xSetFloatVariable <ref>, <string> <float>

Functions to iterate over the local variables in a reference should also be added; i.e. something like
ref, type, name xFirstVariable <ref>
ref, type, name xNextVariable <ref>

xVariableExists should return the type of the variable (short, long, or float).

If an xGet or xSet is used with an inappropriate type, the value should be converted to the desired type (if possible) before being returned or set. (That is, if xGetLongVariable is used with a short, the short should be converted to a long before being returned).

This would be amazingly useful for what I am writing at present

I'm not sure if variables are stored as anything except an index:

Iterating could work though.
