[actionstep-core] Updated variable naming convetion

[Richard K. <ri...@in...>]

All,

I just updated the variable naming convention on EVERYTHING.  The  
double underscore stuff was getting out of hand with __foo__ for  
static/global and __foo for member variables.  Scott and I agreed to  
m_foo for member variables and g_foo for static/global variables a  
while ago and I had not made the change yet, but its in CVS now.

I know that this is the stuff of religious wars (conventions, etc),  
so lets not war, lets enjoy writing code.

Best,

-rich

PS.  Thanks be to Ruby and regular expressions, it was 20 lines of  
code to write a converter.
