BuildInfoPage a link to the lab page, fixed the FlightLevel Major/Minor check

Some BuildPageImprovements :)

1) When watching information about a build, it's not possible to view more builds from that lab without returning to the homepage and searching for lab, so add a link to the labpage

2) Fixed the FlightLevelBadge to show only for ( (6.4 || 10.0) && HasFlightLevel)
