Zotero-TEI export is broken

[dasch124]

• many invalid xml:ids (spaces, unescaped single quotation marks, brackets etc., e.g. belnap r. kirk_2009_3013)
• same xml:id is used for different entries (e.g. behnstedt_1994_0001 is used for @corresp='http://zotero.org/groups/2165756/items/EEI7S3N8' and `@corresp='http://zotero.org/groups/2165756/items/7TMLL9NZ')
• <extent> must be at the end of the entry (currently it's directly following the <title>
• <title> missing in <monogr> of an analytic publication (e.g. http://zotero.org/groups/2165756/items/5SWT5LJ7)
• HTML-Elements inside of TEI (<h2>, <i>)
