Added alarm blend percent (useful for controlling how long an alarm lasts) and a dropdown list is used now if ZM_FAST_IMAGE_BLENDS is enabled
Remove the ZM_BLEND_ALARMED_IMAGES option (not needed anymore, global per monitor now)
Changed default blend percentages and the dropdown list for alarm reference image blend
Added the database update file for 1.26.5 with includes the AlarmRefBlendPerc option
Merge pull request #241 from ZoneMinder/alarmrefblendoption

Add alarm reference image blend percentage option and replace the text field if fast blends are enabled
