// Displays an attachment or a list of attachments
// Currently works with wiki pages and tracker items.
// Parameters: ln => line numbering (default false)
// 		inline => puts the stuff between {ATTACH} tags as the link text instead of the file name or description.
// 		name => Gives the name of the attached file to link to.
// 		file => Same as name.
// 		image => Says that this file is an image, and should be displayed inline using the img tag.
// 		showdesc => shows the description as the link text instead of the file name
// 		icon => shows a file icon
// 		dls => ????
// 		id => Gives the actual id of the attachment to link in.  Might as well just do a straight link in this case...
// 		num => Gives the number, in the list of attachments, of the attachment to link to
// 		page => Gives the name of another page the attached file is on.  The file on that page is linked to instead.  Only works with wiki pages.
// Example:
// {ATTACH(name=>foobar.zip)}
//  comment about attachment, that will be display under attachment informations
// {ATTACH}
