Add setting for UTF-8-BOM

[c72578]

This setting allows to enable/disable writing the byte-order mark (BOM)
in case of UTF-8 encoded CUE sheets.

• Add setting:
  WriteUTF8BOM
  Default:
  WriteUTF8BOM=1
  The setting is enabled by default, to preserve previous behavior.
• For now, the setting can be modified by editing settings.txt after
  closing CUETools or CUERipper:
  Use bool value 0, to disable writing the BOM to UTF-8 encoded CUE
  sheets.
• The setting is available in the CUETools as well as the CUERipper
  settings.txt file.

Settings for creating UTF-8 encoded cue sheets without BOM:

AlwaysWriteUTF8CUEFile=1
WriteUTF8BOM=0

Nice that this setting was added. Tested it with a few cuesheets (ANSI, UTF-8, UTF-8-BOM and UTF-16 LE BOM encoded) without issues.
Although I would vote for WriteUTF8BOM=0 to be the default as I doubt any modern player has issues playing BOMless UTF-8 cuesheets.

@ha-korth, what do you think about WriteUTF8BOM=0 as default?

[ha-korth]

The primary purpose for saving a CUE sheet is CD burning. That should be considered for the default. I don't have time to test right now but I know for example that ImgBurn supports UTF-8-BOM. I don't know if UTF-8 is supported.

I recommend leaving WriteUTF8BOM=1 as default. Characters mangled in ImgBurn and EAC "Write CD-R" when using UTF-8 encoded cue sheets without BOM. I didn't test further.

@ha-korth Thanks for the feedback and for checking ImgBurn and EAC.
