specify php7 incompatibilities in composer

[jeff1985]

The 3.0.0 version is currently not php7 compatible. You can easily verify that by running: vendor/luracast$ find . -type f -name "*.php" -exec php -l {} \; | grep -v 'No syntax errors'

For 3.0.0 version from composer the command shows:

Fatal error: Cannot use Luracast\Restler\Data\String as String because 'String' is a special class name in ./restler/features/bootstrap/RestContext.php on line 4

I also have seen, that you denied to accept a pull request fixing compatibility issues in the master branch. As specified here, the problems have been resolved only in RC6 branch. Please also note, that this pull request is now 6 months old. So it seems clear to me, that you've chosen currently not to support php7 in the master branch.

Currently packagist does not show any maximum php version requirements. Please specify the maximum php version in branches before RC6 to allow composer to output a compatibility warning when trying to install i.e. 3.0.0 on a system running php7.

Agreed 👍 Thanks for contributing to Restler!

On a second thought decided to make it compatible with PHP 7 instead
