Subject: Reverted r1412 to allow hiding command entry on focus lost;
 src/textadept.c If command_entry_completion handles keys first, pressing
 "Tab" after showing completions switches focus to Scintilla without
 propagating the key. If command_entry handles keys first, pressing "Enter" in
 the completion list will be incorrectly interpreted as a normal "Enter"
 press. Reverted to using the "activate" signal to interpret "Enter" so
 command_entry can handle keys first, keeping "Tab" from switching focus.
