Add copyright and licence notices, and a NEWS entry. The data in the new versions is not entirely the same as what ELinks used to have: - Unicode/8859_1.cp: Adds control characters. - Unicode/8859_2.cp: Adds control characters. - Unicode/8859_4.cp: Adds some control characters that ELinks assumed there already. - Unicode/8859_7.cp: Adds three characters. - Unicode/8859_15.cp: Adds control characters. - Unicode/8859_16.cp: Adds control characters and swaps 0xA5 with 0xAB. - Unicode/koi8_r.cp: Changes 0x95 and adds some control characters that ELinks assumed there already. - Unicode/macroman.cp: Changes 0xC6 and removes some control characters that ELinks assumes there anyway.
