Subject: [PATCH] Reduce memory usage of dynamic properties

The dynamic property variants are stored as QList<QVariant>, which unfortunately
results in QList to behave as array-list because of the size of QVariant. By storing
the variants in a vector directly we can eliminate the array-list element pointers.
