Config file location for loadConfig

[UxerUospr]

Using `loadConfig("config.ini")` seems to want to look in the current directory 
(from where the binary is executed). Is it possible to have it always pull from 
where the binary actually is located or should I look at using something like 
`getConfigDir()` or environment variables? When I run it from outside the same 
directory as the binary I get `Error: unhandled exception: cannot open: 
config.ini [IOError]`
