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'
