performance improvement in PhpMatcherDumper
Tests pass: yes
The code generation uses a string internally instead of an array. The array wasn't used for random access anyway.
I also removed 4 unneeded iterations this way (when imploding, when merging and twice when applying the extra indention). A `preg_replace` could also be saved under certain circumstances by moving it.
And there was a small code errror in line 139.
