Added copy ansi color, still little buggy.
- the half charactor doesn't get copied.
fixed a bug where scol is not populated correctly
moved code around.
Input area now adjust width according to text input.
- updated favicon
ptt seems to be handleing receiving large data by backing off.
- so when pasting large chunk of text, better split them up.
Added comments

Changed zh_TW wording about copy ansi
