Reject '/' (slash) character when renaming filenames

[doitamd]

Suggestion

Filenames in each torrent can be renamed using 'Rename...' context menu in content tab.
While some invalid characters such as colon, question mark and asterisk are being rejected, slash '/' is accepted and creates a new folder with a name using characters preceding '/'.
For example, if I happen to try to rename as (by mistake in most cases):

original filename: aaabbb.txt
into: aaa/bbb.txt

It creates a subfolder aaa and put bbb.txt beneath it, which cannot be undone.

Please reject '/' like other illegal characters.

I sure hope this isn't a bug since I use this feature daily and would strongly object to its removal without a suitable replacement. Also dupe of #16834

#17049 Hope allowing remove the folder by renaming it to empty could be a solution for these folders that were created by mistake, instead of banning the character.
