Only set the state of a used rulefile to "on" if it is present in
the %idsrules hash. This happens if it contains at least one rule.
This prevents from showing a rulefile in the ruleset section if, it
does not exist anymore or does not contains any rules at all.

Create this file on first execution of the script if it does not exist yet.
This will allow suricata to imediately be started. Otherwise the ruleset has
to be downloaded and configured before this file has been created and suricata
could be launched.

Now the enabled or disabled sids are stored in a single
hash instead of two arrays, which easily can be modified.
When saving the ruleset, the new read_enabled_disabled_sids() function
will be used to read-in the current (old) saved enabled or disabled sids
and add them to the new hash structure.
After adding or modifiying sids to the hash, the entries will be written
to the corresponding files.

This function is used to read-in the files for enabled or disabled sid
files and stores the sid and their state into a temporary hash which will
be returned by the function.

This commit adds the required backend code to allow switching
between IDS and IPS mode of suricata.
Technically the behaviour of suricata is specified by the rules -
each of them can contain the action "alert" or "drop" (There are
more actions supported but these two are currently the important one)
When running in IDS mode, the ruleset does not need to be touched,
because the default action is "alert". When switching to IPS mode,
the CGI writes a single line to "oinkmaster-modify-sids.conf" which
is included by oinkmaster and modify the action for each single rule
from alert to drop.

Add the option to select the runmode for suricata, wheater it
should run in intrusion detection mode or intrusion prevention mode.
If the option has not configured yet, it defaults to IPS mode.

Introduce generate_home_net_file() which uses the current network
config to obtain the network address and subnetmask for each
available network zone, generate and write these HOME_NET information
into a yaml compatible file which can be included into the suricata
configuration file.

* Rename filename to suricata-used-rulefiles.yaml

* Adjust code to correctly read-in and parse the changed file

The $settingsdir variable is declared in the ids-functions.pl and used to to

* Drop function to show a notice about snort is working.
* Introduce the log_error function which is responsible for log any
error messages. Currently it writes it to a tempory file, which will
be read by the WUI, the message will be displayed and the temporary file
will be released again.
* Introduce a tiny function to easily perform a reload of the generated
webpage.

Directly use the value from the ids-functions.pl for the
location and filename of the tarball which includes the snort ruleset.
This will save to declare this information twice and prevents from any
failures if the location of filname every changes.

If a single sid has been activated and then disabled without doing
any other ruleset modifications only one of the oinkmaster files
for enabled / disabled rules has been modified.
In this case it was possible, that the same sid, was part of the
file for enabled rules and part of the file for disabled rules at the
same time.
