[Firebird-docs] Firebird File and Metadata Security migrated

[Mark R. <ma...@la...>]

I migrated the Firebird File and Metadata Security document. I also 
migrated the Brazilian Portuguese and Russian version. For the German 
version there are no sources in the repository (looking at the 
rendering, this was translated outside of the project).

The chapters are relatively short, which in the PDF rendering leads to a 
lot of whitespace due to page breaks, but for consistency, I chose not 
to use the 'article' document type (which would not do a page break 
after each chapter).

I do wonder if this document really belongs under 'Reference Manuals', I 
think it would be more suitable under White Papers & Presentations..
