Merge pull request #34 from evmcl/1.9.1

Added the cat and catp variables.
Check if a font has been loaded before instead of adding it possibly multiple times.

In some configurations conky terminated after several minutes
with the message: "Conky: you don't need that many fonts, sorry."
Add configuration setting imlib_image_alpha

This option is passed verbatim to both calls to
imlib_image_set_has_alpha. When false, imlib will not merge the alpha
channel when blending the image into the window visual, which means that
own_window_argb_visual will not result in transparent images. The option
is enabled by default to preserve the current behaviour.
