Fix categorytype for Dish & Bell EIT. The wrong values were being set, in particular causing news to be marked as 'sports' and sports as 'series' which would affect certain scheduling decisions.
Reorder and rename the choices in the capture card combo box

To try and reduce some confusion and common mis-configuration the descriptions and order of the options has been changed. The most commonly used options are listed first, through to the least used and similar or related choices are grouped together. Incorrect descriptions such as 'DVB Capture' are replaced by more descriptive strings e.g. 'DVB-T/S/C, ATSC or ISDB-T tuner card'

Warn about reliance on the XMLTV 'TimeOffset' setting which has been
removed in 0.27

The XMLTV specification states that dates and times must be either in
GMT/UTC or specify an offset from GMT/UTC in ISO8601 format. Since the
'offset' setting has caused so much confusion over the years we're
removing it and requiring all xmltv input to follow the specs.

This change also sets the default for this setting to 'Auto' which it
should have been from the beginning.
