Battle of Britain remake of PSS game CodeSVN

Checks if mouse cursor is at squadron

Added MouseMotionListener to map frame

Draws squadron's name below RAF/Luftwaffe symbol. RAF/LW symbol images moved to "images" subfolder

Paints either RAF or Luftwaffe symbol on locations of squadrons' depending on squadron's nationality

Map resized to 1020x690 to make it possible to divide to 30x30 blocks. Window slightly higher - 110px of upper space for messages

Array used for storing squadrons' positions (to paint them on map) has now 300 squadrons capacity - should be more than enough.

Using new extended constructor (added in previous commit) to create new squadrons. Added reading extended data from file to meet the needs of extended constructor

Changes to squadron class. New constructor with all needed data (is not being used yet)

Changed map graphics again to more precisely reflect area of original game map (little edited previous map). New map size is 1254x858

Changed map graphics to more minimalistic (more similar to original game map). New map size is 1200x800
