#601 Remember selected components in installer

[Ede_123]

Hi,

this patch will allow the NSIS installer to remember the components the user selected previously. For this it's using the Memento macros [1].

This means that especially when updating one has not to do all customizations again.

This would fix [bugs:#3669], [bugs:#4475], [bugs:#4801] and [feature-requests:#2356] as well as at least partially [bugs:#4863] and possibly some more I overlooked.

Seems as I forgot the actual patch ;)

Here's an updated patch based on "nppSetup.nsi" from SVN revision 1329.

Would be great if the patch made it into release!
If there are any issues with the patch please let me know (on my machine it seems to work flawlessly, though).
