Harden player bats: location guard for 'cannot find path specified'

Browse Source 
Field report: a remote player ran join.bat from the wrong place (inside
the zip, or the .bat separated from content\/build\) and got 'The system
cannot find the path specified' + dumps -- the relative 'cd %~dp0content'
failed cryptically.

Now each bat: cd to its own dir, verify build\Release\btl4.exe +
content\<egg> exist, else jump to :badpath and print a clear message
('this file must sit in the extracted folder next to content and build;
right-click the zip - Extract All and run it from there').  Verified: run
from a dir with no content/build -> the guidance prints, no dump.
