Log:
- When running a non-executable file, if the program handling the file type is a console
program (e.g. Perl/Python) it should run in the same console as cmd, and cmd should wait
for it. Implement this by using ShellExecuteEx instead of plain ShellExecute, with the
SEE_MASK_NOCLOSEPROCESS and SEE_MASK_NO_CONSOLE flags. (SEE_MASK_NO_CONSOLE does the
opposite of its MSDN description)
- Use NULL as the lpVerb to get the default action ("open" is not necessarily
the default)
- Allow passing parameters besides just the file name
