* fhandler.h (class fhandler_console): Make all variables that 

describe "state" of console to be members of fhandler_console.
default_color is now the color which is set when console recieves
reset command.
* fhandler_console.cc (fhandler_console::fhandler_console): Turn
mouse handling and raw keyboard mode off by default. Initialize
state information.
* fhandler.cc (fhandler_console::set_raw_win32_keyboard_mode): New
function.
* fhandler_console.cc (fhandler_console::set_default_attr): New
function. Reset console attributes to default values.
* fhandler_console.cc (fhandler_console::open): Reset attributes.
* fhandler_console.cc (fhandler_console::get_win32_attr): New function.
Calculate win32-style console attribute based on terminal attributes.
* fhandler_console.cc (fhandler_console::set_cursor_maybe): Use
member variable.
* fhandler_console.cc (fhandler_console::read): If in raw-win32
keyboard mode, encode win32 keyboard events in \033{x;y;z;t;u;wK
sequences.
* fhandler_console.cc (fhandler_console::dup): Copy all state
information to the dup()ed handle.
* fhandler_console.cc (fhandler_console::scroll_screen): Use current
fill-in	attribute.
* fhandler_console.cc (fhandler_console::clear_screen): Ditto.
* fhandler_console.cc (fhandler_console::char_command): Check if we
saw '?' symbol by member variable. Set terminal	attributes on \033[Xm
commands. \033[24m - turn off underline mode, \033[27m - turn off
reverse mode, \033[39m - restore default foreground color.
\033[49m - restore default background color. \033[2000h - turn on raw
keyboard mode, \033[2000l - turn off raw keyboard mode.
* fhandler_console.cc (fhandler_console::write): Set attribues to
default values on reset command.
