Revert "Added 30m and 1h update interval back in"

This reverts commit 7edcb44f994ebc2793c464a6aa8e1e3929268a62.
Made native bookmarks work. The totalTime must be greater than resume in
order for the resume to take effect. Also added custom_resume check to
prevent double prompt when using custom resumes
Fixed race condition on resume causing _totalTime to be 0 when a video
was resumed.
