Bugfixes
Fixed Color int conversion (#3) * Fixed Color int conversion - Color::parseInt will only return RgbaColor (0xffffff is the same as 0xffffff00 in PHP, so an RGBA color with Alpha 0 would've been seen as an RgbColor (implying full alpha)) - Color::toInt will now use pack/unpack to build the int value to avoid platform difference problems * Updated PHPUnit tests to work with travis again * Remove HHVM and PHP5.6 Support (It's still installable, but it won't be tested anymore)
