Version Checking

[gcohen55]

While, off the top of my head, I can't think of anything that can break between versions sense, especially since we're using pkg, I still figure that we should allow installation only on "supported" versions of software that we've tested on.

Since there will be multiple versions of pfSense, we should have a list of supported versions, run the version of pfSense that the script is running on by that list. If the version isn't supported, quit.

We should also give the user an option ( perhaps defined by ENV variable )

SKIP_VERSION_CHECK="true" curl .... | /bin/sh -s

It's a good idea, as long as we're relying only on the script.

Of course, the package itself will handle a lot of this for us, if and when we have this implemented in PHP for the actual pfsense package manager.

If there is little that can break between versions of pfSense, then this seems like a low priority for this particular project.
