Balance/adjust naval target priorities

[Garanas]

Copied from #3985

Here is my proposed changed to naval target priorities. Below is a list of changes, i will log changes as i make them.

• All frigs, destros, and battleships with aa have had their TP simplified (removed t3 bomber in favor of general bombers)
• All Battleships now target T3 navy before targeting generic navy.
• Tempest's TP have been changed to the following

'NAVAL MOBILE EXPERIMENTAL',
'NAVAL MOBILE TECH3',
'NAVAL MOBILE',
'EXPERIMENTAL',
'TECH3',
'ALLUNITS',

More soon

Speaking of, I think that:

• Tech 3 battleships should target Tech 3 Navy, Tech 2 Navy and then the remainder
• Tech 2 destroyers should target Tech 2 Navy and then the remainder

Which is in line with Turin's proposal where units prefer to attack other units of the same tech level. With the exception of AA, by all means.

What if we'd make the Seraphim Destroyer prefer hover over attacking tech 1 frigates?
