Remove abstract operators from BigNumber, rename divide methods in BigDecimal
...
It turned out that there was no value in having a generic interface for operations, when every concrete class could really only accept instances of itself, and more importantly, would only return instances of itself. This was also a problem for division, that cannot be handled in the same way for BigInteger, BigDecimal and BigRational.
Methods changed in BigDecimal:
- dividedBy() is now exactlyDividedBy(), and always calculates the scale automatically
- dividedToScale() is now dividedBy(), and does not not make any assumption on the scale any more

Rename BigDecimal::dividedAndRemainder() to quotientAndRemainder()

This is consistent with the naming of the BigInteger method.

Add BigNumber::toInteger() and toFloat() methods
...
These methods are implemented by BigInteger, BigDecimal and BigRational.
- toInteger() returns an exact value or throws an exception
- toFloat() returns an approximate value

Remove get prefix in method names
...
This improves overall consistency of method names in the project.
For example, it does not make sense to get the reciprocal of a BigRational using reciprocal(), but get its numerator using getNumerator().
List of renamed methods:
- BigNumber::getSign() => sign()
- BigDecimal::getUnscaledValue() => unscaledValue()
- BigDecimal::getScale() => scale()
- BigDecimal::getIntegral() => integral()
- BigDecimal::getFraction() => fraction()
- BigRational::getNumerator() => numerator()
- BigRational::getDenominator() => denominator()

Rename BigRational factory methods
...
- `BigRational::parse()` is now `of()`
- `BigRational::of()` is now `nd()`
This keeps BigRational in line with BigInteger and BigDecimal, whose `of()` factory method accepts a single parameter.
The new way to create a BigRational from two numbers is now called `nd()` for numerator/denominator.

Shorthand "int" and "bool" are now used instead of "integer" and "boolean".
This makes more sense as the latter are not accepted as synonyms in PHP 7 scalar type hints and return types.
