Reinforcements Table.
- All buttons are functional now.
- Changes made in the table are reflected in squadrons next turn
Squadron
- Added squadronReinforce method. Adds planes according to changes made in Reinforcement Table and adds pilots to match their number with number of planes. Adding recruit pilots changes squadron's general experience, of course.

Reinforcements Table - squadrons added.
Added names of squadrons, planes amount and buttons for adding and removing replacement planes/pilots (buttons not working yet).
Added all 18 British squadrons to datafile.

Day's summary shows failed LW missions (different from aborted missions: aborted are when squadron retreats because of heavy losses before reaching target, failed are when squadron reaches target but doesn't inflict serious damage).

Added repairing radar stations, airfield and city infrastructure at the end of day.
Radar Table refreshing every turn now.
New way of estimating success of German missions. Luftwaffe needs to inflict certain damage (depending on type of target) to claim successful mission. Otherwise counted as failed mission.

Cities repair some damage (1 %) at the end of day.
Better end of day procedures.
