When importing from a url (dropbox, url) the import class changes the image title

[rdswd]

Detailed description of the problem

in php/Modules/Import.php the url method changes spaces in the image title to %20. This is added to the image title in the Photo class. I've submitted a PR to correct it.

Steps to reproduce the issue

Upload photo from url or dropbox with spaces in the title.
