Fix file race on windows
Wapty is not tested on windows but at least running make testvr on windows should be done.
Running the go tests generates just 2 errors. Both are inside confi/save_test.go
--- FAIL: TestSaveAll (0.00s) save_test.go:52: rename C:\Users\SCHROE~1\AppData\Local\Temp.status.zip C:\Users\ME\AppData\Local\Temp\status.zip: Der Prozess kann nicht auf die Datei zugreifen, da sie von einem anderen Prozess verwendet wird. save_test.go:66: open C:\Users\Me\AppData\Local\Temp\status.zip: Das System kann die angegebene Datei nicht finden. FAIL FAIL
First error of line 52 means, that status.zip can not be used, becaue it is used by another process. Error in line 66: status.zip is missing.
Thanks, I'll look into this as soon as I get the chance
