Improved image dec. modules & New dummy modules

* Improved image decoding modules:
- Fixed error that appeared after last commit (eebe859f83).
- Changed some functions to use the mem*_t classes.
- Implemented cell*DecSetParameter.

* Created new dummy modules for sys_net (0x0000), sys_http (0x0001),
cellHttpUtil (0x0002) and cellSsl (0x0003).
More dummy modules

* 41 new dummy modules created.

NOTE: I have detached the previous 4 dummy modules of my last commit
(1a85ccbbf4) from the project since they will consume space of the
executable, and compilation time and don't provide anything useful yet,
the same applies to this commit. The only reason to provide this dummy
modules is to avoid that developers have to spend too much time on
creating the template of the module before implementing functions. If
you want to implement a function of any of these modules, add the
corresponding file to the project first.
Some Modules updated to use mem*_t class

cellKb, cellMouse and cellSysutil now use the mem*_t instances instead
of using "u32 *_addr" variables.
Small issue fixed

Experimental SELF decryption support

This SELF decryption feature is not portable and its code looks really
ugly. It is experimental and is meant to save time to developers when
doing tests with SELF files. Besides that, it works (under Windows). :-)

How to use it:
1. Place "scetool.exe" (and "zlib1.dll") into the main rpcs3 folder.

2. Obtain a LEGAL copy of the SELF decryption keys and place them in a
folder named "data" next to the main executable in a format that is
readable for "scetool.exe". That is, following files should be present:
data/keys
data/ldr_curves
data/vsh_curves

(See screenshot in the comments)

NOTE: These are the steps to enable SELF decryption and it applies to
future commits regarding this matter. We do NOT take any responsibility
about the way you obtain the keys or (until we include SELF decryption
into our code) the actions "scetool.exe" (or "zlib1.dll") perform.
SELF decrypter improves & About... dialog added

SELF decrypter improved:
The files 'scetool.exe' and 'zlib1.dll' are no longer needed. Everything
needed is now included in the rpsc3 project. So the only thing you need
in order to load SELF files are the keys. More information about this
matter in my last commit: c1565e55

Warning for devs! There is a lot of spaghetti code in /scetool/. I
fucked up things a bit while trying to include scetool in rpcs3. There
is a lot of unused code there and I need to make sure that everything is
working properly. In any case, the code seems to work stable so
end-users shouldn't be worried about this warning. ;-)

'About...' dialog added:
Well, I have nothing more to say here. I wish you all a nice day!
