Simon Hausmann 105d10dea9 Fix quadratic behavior in QMetaObjectBuilder when writing string table 
QHash::key() is O(n) and we're calling it n times. That can make repeated
calls to the meta object builder very slow, as for example QQmlPropertyMap
when inserting properties repeatedly.

Fortunately this is easy to fix, as the value in the hash map is also the
index, so we can simply iterate over the hash once. With the exception of
the class name, which we have to treat specially to ensure that it is always
the first entry in the string table.
