[default] Use the slice allocator

Browse Source 
The actor's private data created by the compositor is allocated
using g_new(), but since we are allocating a lot of small structures
all the time it's better to use the slice allocator instead.

Also, use a GQuark instead of using a string, so that the quark
lookup is done only once and the rest of the time is just an
integer comparison.
