*Added "Copy Position" to right click to copy the position as a lua table, also works for areas.
*Proper support for OTBMv4 (revscriptsys) map saving/loading
*Improved Item Properties dialog for revscriptsys maps (doesn't save etc. still though, so quite useless for now)
*Fixed several formatting bugs in dialogs.
*Fixed not being able to open 9.20 maps.
*Fixed sprite cache not being flushed when reloading sprites / changing versions (could cause the wrong graphic to show up)
*Extensions now load for versions after 8.6.
