89b60ffbd4 Refactor error reporting 
This commit introduces ErrorReporter, a utility class which consolidates
all of the error logging functionality into a common set of functions.
It also replaces all direct interactions with an ErrorList with calls to
an ErrorReporter.

This commit resolves issue #2209

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

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.
