Got rid of the "(.method-name object args)" method-calling

Got rid of the "(.method-name object args)" method-calling
convention. It breaks package prefixing/obfuscation, and while
sometimes a handy shortcut it obscures how method calls are really
done, and introduces a redundant way of doing them which complicates
code-walkers and (future) attempts at Parenscript compiler
open-implementation facilities.
