F7 (or any Create Folder action) will now support mkdir with path input (like "foo/bar/baz").
Unlike previous behaviour (which was broken for some time anyway), if one creates such folder hierarchy -> one stays in current folder. According the old code I've found, Krusader would've changed the current directory several times according the path input.
What's the way we want when creating a directory (or hierarchy)?
1) Stay in current directory (simplest, now implemented)
2) Go into last created directory
3) Go into directory containing the last created directory
