Describe the bug
When importing a meta4 list, DTA doesn't recognize the xlm tags present, like title and description fields in the file, so the renaming mask doesn't work.
This appears to be similar to solved issue #250

To Reproduce
Steps to reproduce the behavior:

1. Open DTA manager.
2. Add a link, giving it some custom name, a title and a description.
3. Click on '[Download]' or '[Add paused]'.
4. Select the added file.
5. Right click and 'Export To File' -> 'Export As Metalink'
6. Save the 'links.meta4' somewhere.
7. Clear the download manager.
8. Right click and 'Import From File'.
9. Browse for the previously saved 'links.meta4' file (or whichever name was given it).
10. The import dialogue shows up, with the added link, but with the title and description fields blank. Trying to use text or title for mask doesn't work, when pressing '[Download]' or '[Add paused]', as the link is added only with the other elements (name, ext etc.)

Expected behavior
The import dialogue should display the link with the title and description given it. Also, using the text and title masks should add it with the proper filename when pressing '[Download]' or '[Add paused]'.
