Added new fe.Text property msg_wrapped

[oomek]

Allows to retrieve text of the object after word wrapping.

Example nut file:

local t1 = fe.add_text ( "Lorem ipsum dolor sit amet consectetur adipiscing elit", 0, 0, 400, 400 )
t1.set_bg_rgb( 200, 100, 100 )
t1.char_size = 40
t1.word_wrap = true
t1.align = Align.TopLeft

local t2 = fe.add_text ( "sed do eiusmod tempor incididunt ut labore et dolore magna aliqua", 400, 0, 400, 400 )
t2.set_bg_rgb( 100, 200, 100 )
t2.char_size = 40
t2.word_wrap = true
t2.align = Align.TopLeft

local t3 = fe.add_text ( t1.msg + " " +  t2.msg, 0, 400, 800, 800 )
t3.set_bg_rgb( 100, 100, 100 )
t3.char_size = 40
t3.word_wrap = true
t3.align = Align.TopLeft

local t4 = fe.add_text ( t1.msg_wrapped + t2.msg_wrapped, 800, 400, 800, 800 )
t4.set_bg_rgb( 100, 100, 200 )
t4.char_size = 40
t4.word_wrap = true
t4.align = Align.TopLeft

function tick( ttime )
{
	t3.char_size = 40 + cos( ttime * 0.005 ) * 10.0
	t4.char_size = 40 + cos( ttime * 0.005 ) * 10.0
}
fe.add_ticks_callback( "tick" )
