Subject: NudgeOutOfSolid: add a wasn't-stuck result
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=eb6f0e98a7c0e1bcb0e9294a21cf61ac5825cd31;p=xonotic%2Fdarkplaces.git

NudgeOutOfSolid: add a wasn't-stuck result

It can be handy for calling code to know if the entity was initially
stuck (mainly for warnings).
