tex-everyhook{,-doc}: Add version 1.2

The package takes control of the six TeX token registers
\everypar, \everymath, \everydisplay, \everyhbox, \everyvbox
and \everycr. Real hooks for each of the registers may be
installed using a stack like interface. For backwards
compatibility, each of the \everyX token lists can be set
without interfering with the hooks.
