add option to force web server startup

xabbuh · xabbuh · commit 1583fadbe958 · 2015-06-28T16:59:05.000+02:00
The `server:start` command will report an error message when a lock file
does exist.

However, this means that you cannot restart the web server process if
the previously running process terminated accidentally or if it was
terminated by the user without executing the `server:stop` command (e.g.
by using the system's `kill` command or the task manager).

This commit adds a `--force` option that makes it possible to launch the
web server process even if a lock file does exist.
