selection: don't automatically no-op operations if selection isn't enabled

Browse source 
When the client is capturing the mouse, selection can only be done by
holding done shift.

This is why a lot of selection functions are no-ops if selection isn't
currently enabled.

However, there are many cases where we actually need to modify the
selection. In particular, selection_cancel().

Thus, only check for enabled selection when we're dealing with user
input.

Bonus: this also fixes a bug where an ongoing selection were finalized
as soon as the user released shift, even if he was still holding down
the mouse button.
