	=item pushtable

	Pushes a file in /home/httpd/lonTab directory. Currently limited to:
	hosts.tab and domain.tab. The old file is copied to *.tab.backup but
	must be restored manually in case of a problem with the new table file.
	pushtable requires that the request be encrypted and validated via
	ValidateManager. The form of the command is:
	enc:pushtable tablename <tablecontents> \n
	where pushtable, tablename and <tablecontents> will be encrypted, but \n is a
	cleartext newline.
