o fix submit error in forms. i rejiggered ids and didn't update the code to send the right ones for submit.
o improvements to how ajax requests are made. centralizing that code, serializing requests, and adding a gmail style "Loading..." thing (mostly for diagnostic purposes).
o tinymce fixes - still a lot of work to be done. reduced (by way too much) the number of buttons in the toolbar - i'll iron that out today. it's still sizing itself irresponsibly - and i really want a way to get blur events. may need to patch it.
