Download updates (#546)

* Add rename download attempt from preview

* clean up renew cache some to help with readability

* Download on WiFi regardless of metered status  (From Tachiyomi)

* no reason to show md2 beta message for new debug installs

* update clean up downloads to be a little faster and hit some edge cases not thought of before

* fix bug where manga name does not match the file name and was deleting manga downloads of manga with special characters
