Reduce minimum priority of novel bombers to 1 (== LOW)
Reduce GProd contribution of TCLASS_INDUSTRY (and thus GProd in CIV-ABD)
Somewhat improved algorithm for building German fighters
Reduce effect of longitude on navigation
Made failures concentrate towards the start of a raid
Bomber-to-fighter fire no longer depends on airad/radcon; + other ftr tweaks
stats: refactor 'todt' function to hhist.date.ordinal()
stats: new profittimegraph shows how profit (by type & overall) varies with time
stats: added options to control what profittimegraph shows (full/dead/opti)
stats: profit[time[graph]]: add option -a,--after dd-mm-yyyy, filters on date
stats: add -b,--before to profit[graph].  Not needed in profittimegraph

profittimegraph is basically plotting 'profit -b date' against date
Refactored various stuff out, particularly genroute and types
Various routing improvements; not great though
New routing algorithm, and related changes
Make flak accuracy capped by weather, unless radar-guided
Balance: made Wellington generally better (Ac 40, De 7, Fa 2)
Made flak accuracy cap partially apply when radar && window
stats: added profitmonthgraph
stats: fix some bugs in 'profit' and its graphs
stats: added --nolegend option to all the line graphs

Except those which already had it, which wasn't many.
