QoL small improvement: mouse-to-inventory at TAB key

[ElweThor]

AFAIK, 99% of the times I press TAB, in Valheim, is to do something with inventory, so I thought if wasn't it better to have my mouse pointer directly "warped" to the inventory itself, in such case: it could save me to have to move it there again and again.
Just a little QoL feature, maybe with a config parameter to be able to disable it, for the ones who don't like such behavior.
