Marked as deprecated, as this method is moving to E::W::File::Utils::URL
Change to use new module
Fix to use new method correctly
Strip out file-reading code and use E::W::File::Utils::URL instead
Updated calls to moved methods, as they take slightly different parameters
Remove unused module
Explicitly use DataHub::SourceParser and update its instantiation
Explicitly don't import the uncompress method, because of a name clash
General cleanup - all these methods need to be passed a Hub object so thay can check parameters such as web proxies
dynamic_use has moved up a level to EnsEMBL::Root
