AddSig v2.00 -- Signature Editor plugin for PEiD ..

Description:
Complete rewrite of one of my oldest plugins!

AddSig is a plugin that enables you to easily manage your external signatures.
It has a full signature editor, with ratings system.

You can type a signature without spaces, or binary copy from Olly, it will be
corrected anyway.
If you download some UserDB.TXT you can drag-drop it onto the editor window to
import the signatures from the file.

A search-box is provided to easily find sigs, even if you can't remember full name.
If you type 'UPX' then if UPX is at beginning of sig, the list scrolls to there..
If upx is not at the beginning of line, then the whole name is searched and the first
match (if any) is selected..
EG: Typing 'Vaska' would find sig 'RCryptor v1.6d --> Vaska'; and typing 'RCryptor' would
find it too. There is Find-next button to go to next match..

Rating System:
The rating works like this..
+1 for EP only
+1 for less than 9 masked bytes, and more than 20 total bytes
+1 for less than 1/3 of total bytes are masked, and more than 30 bytes total
+1 for more than 50 bytes in signature
+1 for more than 100 bytes in signature

So a signature can be rated 1 (Not very reliable) to 5 (The perfect sig) ..
If a sig gets a rating of 0 an exclaimation (!) is shown..

Also, a signature can be rated Dodgy. This means it is invalid in some way, the reasons are:

Empty Signature
All masked bytes - EG : ?? ?? ?? ?? ?? ?? ?? ?? ??
Signature length less than 8 bytes
Odd number of masked signature bytes - EG : 00 03 45 0? ?? 00 (3 ?, not 4)
Odd number of signature bytes - EG : 00 03 45 0 ?? 00
Bad chars in Sig - Not 0 .. 9, A .. F or ?
Wrongly masked bytes - EG : 00 03 ?5 ?? ?6 00 (4 ?, but in wrong place)

If a sig is dodgy, an unhappy face is shown and Dodgy! Is written next to it ..
