--help/-h should ignore the need for -w

[AndyProk]

When civs is run without arguments, it complains that

Error: World to be used not specified (option -w missing)

Use -h for help
Exit.

Fair enough.
The same message is produced, however, if civs is run with "-h" or "--help". Checks for option flags that will always cause a program to abort after printing out fixed information on the program (like "--help"/"-h", "--version", etc.) should always be made before checks which ensure that all necessary arguments for a normal run have been given.
Since you're also the author of civs-browser, I won't repeat this there but just mention here that that project has the same problem.
