Route GLib debug logging directly to the Finch debug window

Instead of flowing through purple debug, this merges some bits of the existing GLib log handler, and the purple debug printer.

Testing Done:
Open the Debug window an see some `GLib-*` outputs.

* @short_description: a container for a large number of small chunks of memory
* @title: Memory pools
*
* A #PurpleMemoryPool allows allocating many small objects within a single
* memory range and releasing them all at once using a single call. This
* prevents memory fragmentation and improves performance when used properly.
* It's purpose is to act as an internal storage for other object private
* structures, like tree nodes, string chunks, list elements.
*
* Current implementation is not optimized for releasing individual objects,
* so it may be extremely inefficient, when misused. On every memory allocation,
* it checks if there is enough space in current block. If there is not enough
* room here, it creates another block of memory. On pool destruction or calling
* #purple_memory_pool_cleanup, the whole block chain will be freed, using only
* one #g_free call for every block.
