support different table layout for custom timing

Hey all,

The problem

I'm trying to do a system where users can fill up 10-minute slots, between 10:00 and 17:00.
There can be only one user per slot and one activity/slot per 10 minutes.

The Setup

For this i set calendar style Time grouping to Custom and specified Custom time grouping to be

00:00:00,
10:00:00,10:10:00,10:20:00,10:30:00,10:40:00,10:50:00,
11:00:00,11:10:00,11:20:00,11:30:00,11:40:00,11:50:00,
12:00:00,12:10:00,12:20:00,12:30:00,12:40:00,12:50:00,
13:00:00,13:10:00,13:20:00,13:30:00,13:40:00,13:50:00,
14:00:00,14:10:00,14:20:00,14:30:00,14:40:00,14:50:00,
15:00:00,15:10:00,15:20:00,15:30:00,15:40:00,15:50:00,
16:00:00,16:10:00,16:20:00,16:30:00,16:40:00,16:50:00

I also set Hours and Minutes in admin/settings/booking_timeslots to 0 and 10

The module

in the module (theming) code following statement is provided

$half_hour = ($view->style_options['groupby_times'] === 'half');

But my $view->style_options['groupby_times'] is set to "custom" and thus reverts to hour mode.

Possible design errors

On the settings page there is the helptext "The default length of time of a timeslot."
The way i see it this sets the duration of one event, not the length of a timeslot. Timeslot length appears to be based on calendar style alone.

Possible Solutions

What I try to accomplish could be done via 2 ways i think.

1-put extra options in admin/settings/booking_timeslots to set the actual length of a timeslot, so it overrides the calendar style and automaticcally divide an hour (or day) in x parts

2-support the "custom" groupby_times option, and find a way to deal with the string in $view->style_options['groupby_times_custom'] (which is a string returning the top code block of this post)

also, it's available, not avaliable, a small language error that runs throughout the helptexts and var names :)

But I would also like to thank you for the module you've written so far! I think it is and will be a great tool for people like me who search for this functionality.
