A bunch of new features for the bar type tags (%pb, %pv, %bl, etc):

* the bar orientation (horiz/vert) is now chosen based on the width and heigt values (or can be forced).
* the fill direction can now be inverted (fill right to left, or top to bottom is considered inverted)
* It can now draw a slider type bar instead of a fill type (or indeed a slider with a fill type)

To configure the new bar, any (or all) of the following params can be used after the bmp filename (order makes no difference either):
invert - cause the bar to fill in the inverted direction
vertical - draw a vertical bar (not needed if the height > width)
horizontal - draw a horizontal bar (this is obviously the default)
nofill - dont draw the filling bar (this still draws the outline, obviously pointless without the slider param)
slider - draw an image for the slider. The next param MUST be the label of the image to draw. No option to use a subimage here, so the whole image needs to be the image you want on the slider. 

example: %pb(0,0,-,-,-,nofill, slider, slider_image, invert) - draw a boring horizontal progressbar which doesnt fill and only draws the image "slider_image" which moves right to left.

the slider type might need some tweaking. let us know how it goes
