[clutter-text] Don't allow control characters to be inserted

Browse Source 
If an unbound control key is pressed (such as Ctrl+R) it would insert
a rectangle into the text.

Also zero is considered a valid unicode character by
g_unichar_validate so pressing a key such as shift would cause the
current selection to be deleted. The character isn't actually inserted
because insert_unichar disallows zeroes.
