Modified some basic strings

Modified some basic strings as i talked to adytzu and he told me some things. 
bin/sh wasn't found because in the init.rc wasn't symlinked as it should. Instead of /bin/mksh it was /bin/ash. Also i updated the init.rc to include the new file init.cm.rc. Hope logcat will work this time.
Changed also the dpi to 160 like in stock rom.
