Provide help for quick add syntax

[Paul Natsuo Kishimoto]

I nearly re-reported the bug https://bugs.launchpad.net/gtg/+bug/354934. While reading that discussion, I was eventually taken to https://bugs.edge.launchpad.net/gtg/+bug/340510 and finally learned I could add tags implicitly by using "tags:" in the quick add entry.

Given that it is supposed to be a *quick* add entry, I don't think I should have to delve into the Help or Launchpad to learn this. Also, other issues propose further additions to the syntax, and plugins might eventually extend it even further.

I propose a "Help", "Syntax" or help icon button to the right of the "Add" button that would toggle a region immediately under the quick add entry with a concise explanation of the quick add syntax. Or, this information could be displayed in a tooltip. Or, the help icon could be *inside* the quick add entry, at the right side...similar to the 'clean' icon in search boxes in e.g. Evolution.

I'm not sure about the best way to handle this, but I agree that we should improve discoverability of this feature by providing some help. As such, I'm renaming this bug.

I suppose we can firstly create a new task in the "first launch tasklist" that explains the quick add syntax.

I'm talking about the current syntax :

provide help for quick add syntax tags:GTG due:2010-02-20 start:tomorrow

as described in http://live.gnome.org/gtg/documentation.

I added a new branch to this bug. This is a dumb copy paste of the wiki page into a new first run task.
However, it could be a good start! Feedback are welcome !
