Add bAddMaxWeight bonus for increasing player's max weight

[AnnieRuru]

I'm so amazed that my bAddMaxWeight bonus has been added in rAthena long time ago,
rathena/rathena@0b6c542
but nobody actually pull request here before

the reason is this
https://rathena.org/board/tracker/issue-8541-set-maxweight-item-script-error/

[dastgirp]

Why this isn't merged yet?

[AnnieRuru]

don't ask me, ask one of the core developers
Ind has asked me to pull request anything that touch the source code,
until explicitly review by one of the core developer =/

the only thing I'm allow to is scripts

is it safe ?
the bonus is temporary and player can lose it and then become over actual weight?

[AnnieRuru]

the idea is, having an item pouch as accessory to increase player maximum weight limit
and we have been doing MaxWeight += 10000; all this time,
until the bug report in rathena I linked to came out

yes its temporary
if the player unequip the item pouch having this bonus, they will become overweight
( and if 90% weight they can't attack anyway )
the idea is for the players who wants to increase their weight to spam more pots ...
yes this is custom ... already in rathena repo for a long time ...
