[patch] Fix emms-browser-cache-thumbnail not actually using emms-browser-thumbnail-convert-program

[hiecaq]

Hi emms,

Currently emms-browser-cache-thumbnail checks for the existence of 
emms-browser-thumbnail-convert-program, but when actually 
performing the action it uses executable-find to search for the 
convert executable again.  This makes a difference if the convert 
program I with to use is not in the PATH.  The following short 
patch fix this.

Thanks for making and maintaining emms!

Subject: [PATCH] emms-browser.el: Use pre-defined convert when caching
 thumbnails

* emms-browser.el (emms-browser-cache-thumbnail): When actually
  attemptitng to call the convert program, the pre-configured and
  pre-checked emms-browser-thumbnail-convert-program should be used,
  instead of re-searching for the convert executable again.
