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.

Add support for do/while loops
...
This commit adds support for a standard do <statement> while <expr>;
form of statement. While loops were already being supported; supporting
a do/while loop mostly involves reusing code from while loops but putting
the conditional checking last.

notation
Rational implemented...trying to figure out exponential
fix for token bug, also quick fix for the wei and seconds
fixed problem with var...probably a conversion problem for fixed in size capabilities
adding fixed type tests
Removing bitshift and regrouping fixed type tests together
size capabilities functioning properly for fixed types
got exponents up and working with their inverse, changed a few of the tests....something is working that likely shouldn't be
slight changes to how to flip the rational negative around...still trying to figure it out
tests added
updated tests
odd differences in trying soltest from solc binary, let me know if you can replicate
test not working for odd reason
fixed test problem with fixed literals...still need a way to log this error
broken up the tests, added some, changed some things in types and began compiler work
moar tests and prepping for rebuilding much of the types.cpp file
further fixing
