Removing OnlyShowIn / NotShowIn from desktop actions

I fully support Aarons suggestion for the same reasons.

In this case, we should allow adding more options, e.g. adding a title
string and a sentence string, which the Shell can the pick, if it is
appropriate. This is much better than an "only-show-in", which can
cause a lot of trouble, and is also not very flexible.
By going that way, developers don't even have to know the other
desktop shells, they just provide enough metadata to make their
application look good in every DE.
In practice, I doubt that we will ever need these extensions ;-)

So, +1 for removing the only-show-in part from me - I think it is
confusing and will only cause trouble in the long run.
