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()

All BigNumber subclasses now have zero(), one() and ten() factory methods
...
These methods are optimized for re-usability, and other methods now internally use them.

CS fixes
...
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.
