[FEATURE REQUEST] Allow "\" (backslash) and "/" (slash) chars to be used freely

[the-liquid-metal]

At the moment, szyszka prevents \ and / to be used. This design is actually not critical, and only limits szyszka's potential for further development. Some apps already able to manipulate path. Why isn't szyszka like that too?

Suggestion: Remove the prohibition on using the \ and / chars in related rule tabs in the "Add/Edit Rule" child window.

Since there is potentially new path produced by rules, there should be new column in Files/Folders table named Future Path.

This issue is tightly related to #111 and #112.

I mean, just allowing backslash in the regex would be game-changing. I'm having to use single-character classes ([.]) to deal with the fact that I cannot just simply escape a regex character (\.). The Rust regex engine supports this, so it must be something happening at the UI level.
