server: Updated the website

Added more information, made it more responsive

client|server: Added Sentry for reporting errors

client/game/hud: Clean the text of Win/Lowe

The text was keept between games without beeing true, it needed to be clean

server/templates: Add social to the footer

assets/towers.json: Changed the 'soldier' tower range

So it's able to attack something and not be useless

all: Added goreleaser to manage releases

This is a bit special, we are not using 'goreleaser' direclty but a build bin
(placed on the bins/goreleaser) which has some changes that allow for us to
make it work with xgo that is needed to crosscomplile MW to all desired platforms
