Images from Google may get imported with characters not supported on Android

• enhancement

Environment:

• OS: any, but primarily to work around an Android limitation

I'm going to open a PR to resolve the issue:

• yes
• no

Description:
Android storage may use filesystems like FAT which don't support all characters supported in Unix filenames. When syncing to AnkiDroid media with these characters will get dropped. I frequently seem to run into this with images with * in the original URL. The importer should strip these characters so the images will correctly appear on AnkiDroid.

I cannot open a PR to fix this until #64 is fixed.

As a mitigation I've discovered that Anki's "verify media" feature will rename files with weird characters. Still, it would be nice if Migaku Dictionary would do this automatically.
