This commit adds the ability to copy to clipboard hashtags, URLs and timestamps
when long-pressing them.
Some changes in our TextView class related to text setting have been required
and metadata items are now using a NewPipeTextView instead of a standard
TextView.
Six new classes have been added:
- a custom LinkMovementMethod class;
- a custom ClickableSpan class, LongPressClickableSpan, in order to set a long
press event;
- a class to avoid code duplication in CommentTextOnTouchListener, TouchUtils;
- three implementations of LongPressClickableSpan used when linkifying text:
- HashtagLongPressClickableSpan for hashtags;
- TimestampLongPressClickableSpan for timestamps;
- UrlLongPressClickableSpan for URLs.
