InclusionMatcher now accepts multiple arguments
Added Expectation::toContainAnyOf
Remove short array syntax in spec files
Remove short array syntax from src files
Use get_class() instead of self:: in Runner class

This needed to be changed due to some weirdness in 5.3 and the way it
handles late static binding as compared to >= 5.4.
Remove last remnants of short array syntax
Change majority of spec files to use references

Using references is an uglier way of passing variables between closures
and requires the use of the "use" keyword. On the other hand, it's
wonderfully backward compatible.
Add some version_compare checks for $this bindings

5.3 does not support Closure::bindTo, so everything that does that needs
a PHP_VERSION check before hand.
Merge upstream changes into topic branch

This changes new short array syntax values to 5.3-compatible array()
calls.
Add 5.3 to travis tests
Update composer.json to allow >=5.3, not just 5.4
Update fork details in composer.json

The official Pho framework will not be supporting 5.3 (for good
reasons), so this fork will be pushed to packagist under my namespace.
