GUI form typo fix for lcdproc-dev

Also, this form also a mix of conventions for the field labels "Com Port" "Port speed"... That mix happens in lots of GUI forms. I wonder what the pfSense project standard is - each word starts in uppercase, or just the first word? e.g. The OpenVPN Server form has "Concurrent connections" and "Duplicate Connections", and subheadings "Tunnel Settings" and "Advanced configuration".
