GuiTextBoxMulti now will also break lines when encountering a newline character (#97)

Browse Source 
* Fix for issue #94: infinite loop on space-free sequences in text that are wider than textbox bounds

marked no lastSpacePos as -1.
check for a space-char had to come earlier than check for width overrun.
if no space found in this line but line too wide, wrap sequence and start new line with textWidth of last character.
reset lastSpacePos on every new line.

* GuiTextBoxMulti now will also break when encountering a newline character
