installer crashes with empty input

[GoogleCodeExporter]

Using pentoo amd64 default RC2.1 (running inside virtualbox)

Steps:
Select automatic partitioning (auto-prepare)
Clear text entry box for swap size
Select "OK"

I would expect it to give the same error message as when I type '0' in to the 
box.  Instead I get this:
/usr/sbin/pentoo-installer: line 568: [: : integer expression expected
/usr/sbin/pentoo-installer: line 571: [: : integer expression expected
/usr/sbin/pentoo-installer: line 578: 11404-: syntax error: operand expected 
(error token is "-")

Ideally it would be nice to accept 0 or blank as valid inputs and have no swap 
partition, but I'm willing to accept that if a user wants that they should go 
through manual partitioning.
