charcter_popup set to cover all main sheld elements for ease of use and to limit user errors (using the chat input box while having the character's advanced defs popup open)
removed forced coloring from popup menu buttons.
- changed background color of messages selected for deletion
- changed color of delete message confirmation buton
- changed size/height of deletion menu to match normal send_form height (to avoid #chat resizing awkwardly)
- reverted #chat scrollbar to normal display since corners are no longer rounded
- removed corner radius from #chat .mes divs, since they are invisible anyway
- removed large margin-bottom between #chat .mes divs and replaced with a smaller padding. (This makes the delete screen look nicer as there are no gaps between the selected messages)
- aligned deletion checkboxes in the center of the divs and vertical aligned with avatar icons
previous the input bar would expand to the fit the size of the typed input, but when it was sent, the bar would stay the same size. Now it will auto-shrink back to default size after sending the input to AI.
