Directives: Output directives

dbCGI's output directives all have an effect on dbCGI's output either within the directive, or for the remainder of the file.

<sql quiet>	- define a range in which no default output is generated.
<sql loud>	- define a range inside a quiet directive in which default output is generated.
<sql silent>	- define a range in which no default output is generated, and directives are ignored, but Formatting escapes are still processed.
<sql comment>	- define a range in which directives and formatting escapes are ignored, and no default output is generated.
<sql htmlmode>	- turn on HTML mode output even if dbCGI is being run from the command line.
<sql noheader>	- suppress the default HTTP headings.
<sql binoutput>	- produce a binary output format.
<sql setcookie name>	- set a cookie on the browser.
