Reworked textios to query JSON output from Icinga

Currently broken:

	- Nagios
	- htmlios

The first URL in ~/.textiosrc has changed:

	monitors=(
		foo
		icinga
		'https://your.icinga.example/cgi-bin/icinga/status.cgi'
		'https://your.icinga.example/cgi-bin/icinga/cmd.cgi'

		...
	)
textios: Host problems can be acknowledged
Workaround for "only hosts" lists
textios: Add "-H" to show all host states
Reimplement support for Nagios
textios: Made user interface more intuitive

	-a	Show *everything*
	-w	Include services in state WARNING
	-[SAD]	Reveal soft states, acked problems and hosts/services
		in scheduled downtimes
	-h	Only show hosts

Common use cases:

	- To see what needs your immediate attention:
		$ textios

	- To see everything:
		$ textios -a

	- Show all hosts (in order to easily schedule downtimes):
		$ textios -ah
Update documentation
Reimplement htmlios using JSON
textios: Remove duplicated check
Update manpage for htmlios
Fix file system collision

textios wants to delete /tmp/textios-* which includes /tmp/textios-data.
Adjust style for ACKed services
htmlios: Do not show host info with "-o"
htmlios: Bugfix: Don't show host info for excluded hosts

Previously, only service info was excluded.
htmlios: Complete example in manpage
texios -c: Recursive copy
textios: Document "-c"
Manpage: Consistent style for redirections
textios: Easter egg
htmlios: Skip special location name "NONE"
