Awakening Encounters Renovation

The first couple times I played through Awakening, I legitimately did not even know it had random encounters.  Nor did I know that Velanna had a personal quest.   -_-

Awakening doesn't use the same encounter system as DAO, instead hiding exactly how encounters are triggered behind incomprehensible code, but I did manage to remake the world map travel system, using Origins' system as a base.

The result is that encounters, especially unique encounters, like the ones for Velanna and the sword Dragonbrand, are much easier to get now.  Also, new encounters can be added via .gda extensions, which I admit is more niche, but still a nice side effect.

(1. 4) I think I finally solved the repeating unique encounters issue.  Hopefully.  (turns out the bitwise encounter tracker didn't like my renamed variables 😑)

Please remove the old version when updating to 1. 4.  If installing/updating mid-playthrough, you will may revisit a few specific encounter maps, once each, with the enemies already dead.  The game will keep track properly after that, however.

If you want the gritty details:

How Origins determines random encounters is to first decide if a trip via the world map can have an encounter.  It does this by keeping track of how many times you travel via the world map, and checking a table to see if that trip# is eligible.  If the check comes back 'yes', it then goes through the list of encounters for that terrain type, and rolls a random number (1-100) to check against the encounter chance.  If the RNG is less than the encounter chance, it then checks for repeatability - if an encounter is non-repeatable and has already been done, it's rejected. If the encounter passes, it then checks for plot conditions. If you've met plot requirements, the encounter triggers!  If not, it goes to the next encounter on the list until it either finds one that can run, or returns you to normal map travel.

In Awakening, however, the system is largely hidden inside the gxa_module_travel.ncs, which, if opened, is largely computational gibberish with some recognizable strings scattered about.  One of the strings seems to be a function called "GXA_CheckRandomEncounter", hinting at different conditional checks.  The game still calls on the various rand_***.gda files for some things, which is why simply increasing encounter chance in those files does help a bit.

As if the weird encounter check system wasn't enough,  Awakening also wasn't even trying to call random encounters very often -- only about 1/3 of trips on the world map were eligible for random encounters (as determined by enc_trips_gxa), as opposed roughly 3/4 in Origins (determined by enc_trips_sp).
