Implemented: New TWiki::Func::extractParameters Function to extract all parameters from a variable string

extractParameters( $attr ) ==> %params

• Example:
  • Variable: %TEST{ "nameless" name1="val1" name2="val2" }%
  • First extract text between {...} to get: "nameless" name1="val1" name2="val2"
  • Then call this on the text:
    my %params = TWiki::Func::extractParameters( $text );
  • The %params hash contains now:
    _DEFAULT => "nameless"
name1 => "val1"
name2 => "val2"

This function complements the existing TWiki::Func::extractNameValuePair function. TWiki::Func::ExtractParameters is faster if you have several parameters to extract.

This was a simple addition for Cairo, so that Plugin authors can use it if needed.

After Cairo we can improve some places of the core code that use repeated extractNameValuePair calls.

I am aware of Crawford's Attrs function. The Attrs parsing differs from TWiki::Func::extractNameValuePair; Wiki::Func::extractParameters parsing is the same as TWiki::Func::extractNameValuePair.
