a6faa5acf3 Treat returns with expressions as return param use
There are many cases of code where the return parameters exist mostly
as a form of documentation.  This change ensures that they do not have
to be used in the function body so long as there is a return supplying
values

a40c8cfb68 Warn on unused local variables
Analyze functions for all local variables, parameters, and named
return variables which are never used in the function, and issue
a warning.

e544698ad3 Deprecate use of unary '+'
The unary '+' serves no meaningful purpose in Solidity and it makes it
possible to produce typos with dagerous implications (e.g. 'a =+5 '),
so we are deprecating it.  The SyntaxChecker currently issues warnings
on the unary '+' but will still compile it for now.
