Turn filename separators into dashes rather than dropping them

Browse Source 
Splits the forbidden set: / \ | : were separating words, so they become
"-"; ? * < > " ' just go. Runs of dashes and spaces collapse to " - "
when the run held whitespace and to a bare "-" when it did not, so
"Show | Series" reads "Show - Series" while "AC/DC" stays "AC-DC".

Forbidden characters are now split in two. Separators (`/ \\ | :`) become `-`; the rest
(`? * < > " '`) are simply dropped. A run of dashes and spaces then collapses to `" - "` when the
run contained whitespace and to a bare `-` when it did not, so:
| input | output |
|---|---|
| `Get in the Trunk \| Anthology Series \| Delta Green` | `Get in the Trunk - Anthology Series - Delta Green` |
| `Ep 12: The One` | `Ep 12 - The One` |
| `AC/DC` | `AC-DC` |
| `well-known.mp3` | `well-known.mp3` |
| `../../etc/passwd` | `etc-passwd` |
Leading dashes and dots are trimmed too -- a filename starting with `-` trips up CLI tools.
**Worth knowing, not a bug:**
