InsertTasks in link form

[linuxcaffe]

The InsertTasks command has the potential to make a superb task "dashboard", embedding queries into a wiki page with your regular activities, deadlines and current projects, etc.
While arranging a page to do this, I find myself creating descriptive headings above the "%%TaskList: " line, and while that works ok, it has a redundancy and a "double list header" that could be improved.

So the idea here is to embed the %%TaskList: in the form of a vimwiki link. something like this;

[[%%TaskList: +DUE +work desc.startswith:call|Work Calls]]

All of which would be concealed but the "Work Calls" part, unless the cursor were over it.
This could stand alone or be used in a heading, or as a list item, and the output should respect indentation.

A vimwiki link typically goes somewhere, but hitting enter on this one should invoke UpdateTasks, maybe even reload the page, in case external changes have occurred.

There has been some discussion of "executable links" on the vimwiki github site, which may (or may not) be helpful; vimwiki/vimwiki#19

With regards to highlighting, because this form is always intended to be the header of a list, it might be a good visual cue if this link-type was always underlined when concealed, but that would be icing on the cake!
