Gtt report output to xlsx format and time_format as seconds, cells are still string

[daften]

When you want to use the report data in excel, I'd expect numeric data to be a number formatted cell in excel, so I can e.g. use autosum.
At the moment when outputting time_format as --time_format="[%seconds_overall]", the output cells are strings and summing a column e.g. with a condition on a certain user, gives me 0 as the total. I could easily create custom reports with totals by user based on the records sheet, if the numbers data was actual numbers. Can this be changed?

Thanks for this incentive to get me to overcome my laziness of formatting the cells :)

Yes, I'm sure it's possible, I just made the simplest possible implementation and preferred due to the reason above to just correct the cell type from excel directly.

I'll try to get a PR in during the weekend.
