[PATCH] inform user if any postinstall script failed to run

[Jon TURNEY <jon dot turney at dronecode dot org dot uk>]

Here's a small patch for setup.exe which causes setup to indicate if a 
postinstall script didn't run successfully.

This should help avoid the situation where the postinstall scripts fail to run 
and the user has a broken installation, but they don't notice until they try 
to run something which relies on postinstall scripts, e.g [1] and I'm sure 
there are other examples.

ChangeLog:

	* postinstall.cc : Note if any postinstall script fails and tell
	the user with an error messagebox
	* script.cc (run): Don't rename script as .done if it didn't run
	successfully
