Add ability to copy hashtags, URLs and timestamps in descriptions on …
…long-press 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.
