* digidisplay by cheapie (re-implementation of "textline", displays text in
multiple sizes, not entirely unlike LCD's, but bigger text)
* simple_steetlights by me (makes building street lights nearly effortless)
* street_signs (common street name sign, i.e. the 2-up green ones on most street
corners, forked from signs_lib)
also updated mesecons and pipeworks
