[NTG-context] [Wiki] list of editors

Ahoi! I reworked https://wiki.contextgarden.net/Text_Editors The split into "ConTeXt aware" and other editors didn’t make sense since they got mixed, editors that are Unicode-disabled we should just ignore, and the table had too many columns. If you know one of these applications better, please add the missing features. Additional features that *I* look for in an editor are e.g. project management (at least a directory tree view) and git client. But maybe that’s out of focus for that table.
