Reimplementing layouts for the connection panel
This is mostly functionally equivilant, but a sane implementation (there was a lot of headaches and voodoo in figuring out where previous measurements came from), plus has better space allocation. Columns have priorities for determining which are shown in the limited space. However, we're now fitting in lower priority entries that fit even if there isn't room for a bigger but higher priority column.
added: smarter space utilization, filling in smaller columns if there isn't room for higher priority but larger entries
fix: trivial crashing bug when fecthing relay nicknames
