the assetSize in the db was set wrong. This happened when a File/Image
was added, and when it is committed. Editing the Asset would fix it, but
once it was committed, the files in the Storage area were not added.
List of Changes:
1) Removed setSize from File/Image.pm. It can inherit from File.
2) In Asset::File::processPropertiesFromFormPost, set _storageLocation to the Storage
object. Remove the call to setSize since it's done in ->update
3) In Asset::File::setSize, fetch the current storage object via getStorageLocation.
4) In Asset::File::update, move the call to update after the filesystem work. This
way changes in the size of the permissions file get accounted for.
5) In Asset::update, call setSize after all changes, regardless of whether or not
properties have changed.
6) In Asset::setSize, refactor out the size calculation and update $self's properties
cache so that long running scripts have the right size.
