rat-commander (rc): download ældre versioner

What's new
- Shift-F6 now renames the file under the cursor in place. The prompt is prefilled with its current name and the new name stays in the same folder. With files marked, Shift-F6 still opens Multi rename, and Ctrl-F6 always does (#25)
- Fixed mouse movement over SSH sometimes being read as an Esc press plus stray text like [<35;60;26M. This closed open dialogs, typed into the command line or quick search, and made wheel scrolling jump around (#26)
- Fixed pasted text losing a character every 65 characters in the command line and the editor. The same bug also dropped events during fast scrolling and key repeat

What's new
- Portable mode: if a file named portable sits next to the executable, all settings are kept in a config folder beside it instead of the platform config directory. The Windows .zip now ships with this marker, so it can run from a USB stick without touching %APPDATA%. Delete the marker to go back to normal. This works on Linux and macOS too (#20)
- New sort keys: change time, access time and birth (creation) time. The panel menu now has a Sort order submenu that shows the current key and toggles (#23)
- "Directories first" can now be turned off to sort folders and files together (#23)
- Symlinks to folders can now be entered and are sorted together with the folders (#22)
- Fixed a linking error when building on illumos and Solaris (#24)
