Add: Full support for sid-msg v2 format which
enchanced by the following fields: gid,revision,classification,priority
for each entry which allow pre-population of signature metadata by barnyard2.

The feature could still have some bugs but it should be stable enough
for pre-prod environements.

Add: spo_database keyword "disable_signature_reference_table" which
allow a user to tell the output plugin not to populate the sig_ref table
thus speeding up the startup process when there is alot of signature in
use and that the table is not used for any reason.

Bumped: Build to 323
SIDv2 commit.

Bumped: Build to 324

Enabled: Variable resolving in configuration (generic variable)

Fixed: some sidv2 code
Fixed: sid-msg.map and gen-msg.map double declaration issue (using
       command line and directive is now prohibited) [ will bail
       if both are used (-S and config sid_file OR -G and config
       gen_file.]

Note: This commit will probably change before official beta, so if you
use this its at your own will and risk.
ADD:  Signature Suppression support at the configuration level.

examples:
config sig_suppress: (GID):(SID)  GID is optional
and SID can be a single sid or a range like below.

config sig_suppress: 10-40 <= RANGE
is equivalent to
config sig_suppress: 1:10-40 <= RANGE
or also equivalent to
config sig_suppress: 10,11,12,13,14,15,16....,38,39,40 <== alot of
single entries ...less effective :)
but not equivalent to
config sig_suppress: 122:10-40 <= RANGE

config sig_suppress: 1:10,20,1:30,2:90-102
config sig_suppress: 1:10,1:30-40,15,10-40,25
config sig_suppress: 1:10,50-55,15,10-20,80,51-52,31-35
config sig_suppress:
2:93,2:95,2:100-101,2:91-122,22-27,2008175,2657,2011766,9900009,2001972,2101623

So with the example above the final list is the following:
