Large pile of various optimizations and small bug fixes. Changeset has a great regression risk, blame me on new odd bugs.

 * default alignments/expandratios now not transported over uidl
 * added new map type to painttarget
 * rewrote UIDL with overlay type
 * ditched gwt JSON implementation instead of own "overlay type" altogether
 * using arraylist instead of vector in all places on client side
 * optimized a bit LocaleService
 * rewrote uidl browsers in debug window (now does not stall IE that easily with large changesets)
