use g_intern_string for static caps

The registry objects statically allocate quite some memory. There are two big
consumers of memory:
1.) the registry-object instance (GstPluginFeature, ...)
2.) the strings (names, klasses, descriptions, ...)

On 2.) we already use g_intern_string for a few of them. 1.) could be solved in
0.11 by e.g considering GstMiniObject.

The attached patch uses g_intern_string also for static caps. This lowers the
allocated memory on my system from 1683kb to 1233kb.
