added: a new way: HEX format to saving/reading from PostgreSQL bytea columns

Browse Source 
added: to Request:
       // binary page
       BinaryPage binary_page;

       // a compressed page ready to send to the client
       BinaryPage compressed_page;

       // if true then either page or ajaxpage will be sent to the client
       // if false then binary_page is sent
       // default: true
       bool use_text_page;

       BinaryPage is defined as (in requesttypes.h):
       typedef PT::TextStreamBase<char, 1, 4096> BinaryPage;

added: to Compress: now it can gets BinaryPage as arguments (input, output)
changed: winix version to: 0.5.0
added: in templates: TexTextStream class
       for taking input to the TeX typesetting system
