added version without javascript to hb_cronjob

to update the HVW data with an external cronjob (just php)
...index.php?option=com_hbmanager&task=updateHvwDataCronJob

with JavaScript
...index.php?option=com_hbmanager&task=updateHvwDataCronJob&js=true
added a plain view for cronjob 

index.php?option=com_hbmanager&task=updateHvwDataCronJob&format=raw&viewoption=plain

no viewoption => php / HTML
viewoption=js   => JavaScript / HTML
viewoption=plain => php / no HTML
changed hvw data handling (only hbdata so far)

- changed hb_spiel (and hb_mannschaft) DB table
- changed the way HVW data gets stored (only schedule, no ranking and all games in one table)
--> this is a major change so rest of component and other components and modules won't work anymore
