Decimals v0.5.0

This version, 0.5.0, brings huge changes, some of which are breaking.

All of the supported arithmetic operations have been rewritten in order to comply with the decimal floating-point standard. Correctness of the new implementation is supported by a large test suite ("dectests").

The user facing changes are the following:

conversions between Decimal and numbers from Base has changed
parsing Decimals from strings has changed (and is now more complete)
the arguments of normalize and round functions are different
users can set so-called context to change the precision (which used to be constant), rounding mode, and minimum/maximum exponent

The current state is described in the new documentation webpage available at http://juliamath.github.io/Decimals.jl/.
