Add tex-filehook{,-doc} 0.5d

The package provides several file hooks (AtBegin, AtEnd, ...)
for files read by \input, \include and \InputIfFileExists.
General hooks for all such files (e.g. all \include'd ones) and
file specific hooks only used for named files are provided; two
hooks are provided for the end of \included files -- one
before, and one after the final \clearpage.
