Added new functions to the search '-s' argument

[Bl4ck-C4t]

I have added the text2 and the regex methods that can be used to find vulnerabilities easier by adding more extended searches.

Usage: vfeedcli -s text2 "Linux Escalation" - this will show all queries that have BOTH "Linux" and "Escalation" in their description. vfeedcli -s regex "Ubuntu 4\.\d" - this will will use the regex expression to find all queries that have "Ubuntu 4." followed by any digit.

Thanks a lot. Let me tested before acceptance.
