#1894: Various cosmetic bug-fixes/improvements to program guides

 I have some channel icons that contain transparency information. The code
 that displays the channel’s call sign underneath the channel icon was
 causing me some problems because the text was visible through the
 transparent icons. The attached “guideicons.patch” file tweaks this code
 so that the text is only displayed if there is no channel icon configured
 for a given channel. It also contains a minor optimisation so that if the
 channel icon contained within the database cannot be located on the disk
 the cached icon filename is reset so that the guide doesn’t keep trying to
 load the same icon each time the channel is visited in the guide. I found
 that this greatly improved the scrolling performance when icons are
 missing for one reason or another.

 Whilst I was looking into these problems, I noticed that the large
 (current) channel icon had a black background behind it, yet the smaller
 (per-channel) icons displayed in the main guide list did not. I discovered
 this black background came from the theme background images. I personally
 think that it looks better without this black background so I have
 produced some modified background images with the black square removed.
 “gg-backgrounds.tgz” (containing updates for both “default” and “default-
 wide” versions)

 I also noticed that the “gg-vid-background” images (used for the program
 guide whilst watching TV, with the video in the top right-hand corner)
 differed from the “gg-background” images (used for the main program guide,
 without the video in the top corner), with respect to the current date
 being placed in its own box. Again, personally I think it looks better
 without the box, so I’ve made them both the same.

 Along the way, I came across some minor problems with the “MythCenter” and
 “MythCenter-wide” themes. I’m not sure that I can remember all of the
 tweaks, but they include; video overlay not exactly lining up with
 background “Loading Preview Video…” box, “Loading Preview Video…” being
 over-drawn on the video feed whenever the cursor moved in the program
 guide for the “MythCenter-wide” theme, channel icons being
 stretched/distorted, the channel identification area being a different
 size between the video overlay guide and the normal guide. These changes
 were all tweaks to the MythCentre theme XML files and are contained in the
 attached “MythCenter.patch” and “MythCentre-wide.patch” files.
