Readded the hello world plugin. Host apps, which do not want to see it,
should simply ignore by adding it to the list given as first argument to
PluginLoader.

Added ImageCollection::isValid().
I realized that there was no way for applications like digikam to indicate
that there were no album selected. So to indicate that an image collection
is invalid, the host application should give 0 for ImageCollectionShared
pointer on construction of ImageCollection.
This will make ImageCollection::isValid() return false.
Plugins should now test for isValid() before using data from image
collection.
