Added character portraits.

Minor update fixes some text.

-Added an exploration bonus (truck) and lore in the fields to the south.
-Added Ava conversations x 2
-Added hints to game lost screen.

Changed some text to help it fit in the new text box layout.

Changed some of the intro text. Added a day 38 when reinforcements arrive from Kirkwall to clear the map for you of any remaining (stuck) infected.

Tweaked the dialogue on the 24 day message to remind you about the directions of the last wave and to not lose any key units at the last hurdle.

Removed infected entities that might on a rare occasion spawn in the trees and make it impossible to finish the map (even though they should be spawning in open grass).

Fixed a typo. Thanks ImKibitz :)

Dialogue between waves has been tweaked to make it clearer which way the next wave will be coming from.
