Win: Rearrange start menu entries

[LapTop006]

I strongly suggest two changes as recomended by the "Designed for Windows
XP" logo requirements (Version 2.3, section F1.1).

1. Remove the "Uninstall Inkscape" option. This ability is already
available from the canonical location of Control Panel->Add or remove
programs, and is strongly recomended against:
"Do not place shortcuts to remove the application in the Start menu. It is
not needed because your application’s uninstaller is in the Add or Remove
Programs Control Panel item."
Further to that, it's an option that will only ever be used once and having
it there is of no benefit to users.

2. If this is done, no longer create the "Inkscape" start menu folder, just
create the inkscape item, as per:
"If any additional shortcuts beyond the main executable are required to be
on the Start menu, then these should be placed in a subfolder using a
<publisher\product> hierarchy."

This (slightly) increases system usability with no penalties.

confirmed.
I also removed the default ticks for desktop and
shortcut-bar as this is according to the Microsoft document.
Committed into the SVN.
