#3 openwebload cannot be run non-interactive under Unix

[Lars Windolf]

Due to the keyboard handling the tool cannot be run without an interactive shell.

$ echo | openload -l 10 http://www.example.com

$

The key handling seems to abort the program immediately.
Disabling it is a workaround: I uncommented the call to checkStdIn()
in src/event_loop.cpp

A good solution would be to not check for keyboard input when
called non-interactively (e.g. specified by an additional command
line switch).
