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

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

+/*
+	TexTextStream is used as a buffer for creating a html page
+	By default all operators<< escape its string arguments. If you don't want
+	to escape an argument you should use a helper function R() (raw argument)
+	note: you have to define the function yourself, we do not provide it
+	because such a short name would make a mess in namespaces
+
+	sample:
+	create a helper function R as follows:
+
+		template<class RawType>
+		TexTextStream::RawText<RawType> R(const RawType & par)
+		{
+			return TexTextStream::RawText<RawType>(par);
+		}
+	
+	now you can use TexTextStream in an easy way:
+		TexTextStream page;
+		std::string key = "some <b>string</b>";
+		page << key << R("<h2>html goes here</h2>");
+
+	// !! UPDATE INFO this is TEX text
+	only html tags "<b>" and "</b>" will be correctly escaped
+
+	currently following characters are escaped:
+	 <  -> &lt;
+	 >  -> &gt;
+	 &  -> &nbsp;
