Parse a request and return 'lorem ipsum' string accordingly

Command format:

	c[haracters] [case] [number_of_characters]
	a[lphanumeric] [case] [number_of_characters]
	w[ords] [case] [number_of_words]
	s[entences] [case] [number_of_words_1 [number_of_words_2 [...]]]
	l[ist] [case] [number_of_words_1 [number_of_words_2 [...]]]

	where case is { u[pper] | lo[wer] | t[itle] }
	and number_of_words is an integer or a multiplication (for example '3*6')
	
	commands can be shorten by using initials. For example, "wt 9" is equivalent
	to "words title 9"
	
	see examples at the end of this script
