Fix the translation script.

The translation script was missing the first character of the line when it was a quote.
Re-enable the option to bypass the DVD/BD path selection.

This option wasn't doing anything on Vista+ OSes and was just setting the default path for the selection dialog on XP.

Also reword the option to make it clearer.
Really fix the translation scripts after 626acc16438ac90af186ef984de4fb18cf93fd37.

The patch script was duplicating the first characters when they were quotes.
DSUtil: Added default value for escape character.
Changed parameter order of ExplodeEsc since the escape character will be rarely specified.
