Test broken in master

[gianarb]

Hi! I'm trying to fix issue #99 but this test is broken in master branch https://github.com/zendframework/ZFTool/blob/master/tests/ZFToolTest/Model/SkeletonTest.php#L60 because Skeleton::exportConfig($config) don't return a string but a different array.

https://github.com/zendframework/ZFTool/blob/master/src/ZFTool/Model/Skeleton.php#L84-86

@gianarb is fixed in master branch

@gianarb I fixed the issue, the behaviour of Skeleton::exportConfig($config) is changed in the meantime. I casted to string and adapted to the new output here: https://github.com/zendframework/ZFTool/blob/master/tests/ZFToolTest/Model/SkeletonTest.php#L60
