Fixed bandwidth calculations. Now they use the default UAVO metadata
when the cell is empty.
Attempt at deleting cells. Works moderately well, but has a weird bug by
    which a cell must be clicke on after it has been deleted.
Prevent cursor selection of "Default" and "Current" columns.
Added +/- buttons for adding and removing columns.
Provided double-click functionality for changing header text.
Change import method to not fill cells with default value, but to instead
leave them blank.
Import method no longer uses previous values for subsequent column entries.
WIP: Added dialog box. Loads values, but does not currently return them.
Added all functionality to metadata dialog box.

Made several small style fixes.
Changed QList to QVector.

PiOS MPU9150: check irqs are occuring before starting task
PiOS MPU9150: check for failure to configure

Right now we only check the first register writes which is probably
ok but not great.  It is important to do something though otherwise
the while loop when setting the sampling rate can trigger resets
as opposed to sensible diagnostic codes.
PiOS MPU9150: make more functions return success/failure

Removes the while loops that would loop infinitely until success.
This blocked diagnostic codes and led to resets.  Now the panic
LEDs or whatever can be performed from pios_board.c
Added several tooltips to telemetry scheduler.
