functions: added assertion_non_equal

Browse source 
This function takes three arguments:
etxt - the text to be logged if the assertion fails
var1 - first variable to compare
var2 - seconf variable to compare

The function compares 'var1' and' var2'. If they match it logs 'etxt' and
raises exception which will abort profile loading.
