Big Transcriber update

BSSScribe – a Tengwar, Cirth and Glagolitic transcriber was updated.

Internal "raw syntax" codes were updated.

New:

• Now it's possible to address alt font glyphs directly using sequence BACKSLASH SPACE <CHARACTER> (e.g. "\ x");
• All fonts were moved from wiki/ into transcriber/ folder;
• Tengwar Optime Diagon font was moved to italic variant of Tengwar Optime;
• Link to compare with Tecendil's result;
• some bugs.

Fixes:

• Crash on raw codes for "upside-down" tehtar;
• Many cases of wrong transcription after escape characters (\);
• When a sequence of tehtar was inside one raw code block (inside braces {} separated by | or /) only one of them was shown;
• Removed double space after punctuation marks;
• "au" in the Mode of Beleriand;
