/usr/sbin/bootmanager: Speedup yeslist_func by using
ash instead of sh and bypassing the slow for loop on the myriads of modules.

Minor thingis :
     Use elif instead of many if .
     Use MY_SELF instead of action bootmanager to be able to run several versions that are renamed.
     Several geany formatting fixes.
     Make yaf-splash compatible with the binary version of Puppy-4.
