Major plugin refactor and cleanup.

Switched to POCO library for unified platform/library interface.
Deprecated the external module API. It was creating more problems than solving.
Removed most built-in libraries in favor of system libraries for easier maintenance.
Cleaned and secured code with help from static analyzers.

+ Building WCELIBCEX library
+--------------------------------------------------------------------------------
+
+*** IMPORTANT ***
+Remember to build WCELIBCEX as a static library, not DLL.
+Provided project for Visual C++ 2005 is configured to
+build WCELIBCEX as a static library
+*****************
+
+Supported and tested platforms:
+
+- Windows CE 4.x
+  - Pocket PC 2003
+  - Smartphone 2003
+- Windows CE 5.0
+  - Windows Mobile 5.0
+  - other custom operating systems based on Windows CE 5.0
+
+If you've used WCELIBCEX on Windows CE OS not listed here,
+please drop me a message on mateusz@loskot.net.
+
+Supported compilers:
+
+- Microsoft Visual C++ 2005 Standard or Professional
+- Microsoft eMbedded Visual C++ 4.0
+
+At the moment, there is no project file available for eVC++ 4.0.
+The process of creating new project file for WCELIBCEX is pretty easy,
+so there should be no problem with creating it for eVC++ 4.0.
+In case of problems, write to wcelibcex-devel@lists.sourceforge.net.
+
+Building the library
+
+1. Go to 'msvc80' directory
+2. Open 'wcelibcex_lib.sln' project in Visual C++ 2005 IDE
+3. From the main toolbar, select prefered 'Solution Configuration'
+   and 'Solution Platform'
+4. Run Build -> Build Solution
+5. If no errors occured, the library is ready to use
