Change Log for Console Application Runner Classes

v3.1.0 of 11 August 2014

Added new UnicodeEnvironment Boolean property to TPJCustomConsoleApp that enables a Unicode environment block to be passed to child processes.
Fixed bug preventing compilation of FireMonkey demo projects 4, 8 & 11 in Delphi XE4 and later by conditionally including the required FXM.StdCtrls unit for those compilers.
Added new demo project #13 that demonstrates the use of the Environment and UnicodeEnvironment properties of TPJConsoleApp.
Minor corrections to code comments.

Fixed problems with compiler directives in PJConsoleApp.pas, demo project #12 and Echoer test application that were causing compilation to fail on Delphi XE5.
Minor documentation tweaks and corrections.

The PJPipes, PJPipeFilters and PJFileHandle units were all removed from the project. They are now part of the I/O Utilities Classes project.
Modifications made to support compilation with Delphi XE2 and later:
- Unit names references in project source files are now qualified with the unit's namespace name when compiled with Delphi XE2 and later.
- The reference to the Graphics unit was replaced with System.UITypes in Delphi XE2 and later to remove the unit's dependency on the VCL permitting its use in FireMonkey projects.
Updated demos:
- All VCL demo form fonts changed to Arial 9pt.
- VCL demo forms are no longer scaled.
- Provided read-me file to explain how to build demos.
- Improved project and config files so all dependant files can be found by all supported Delphi compilers. ~~Fixes Issue #24.~~
- Added a new FireMonkey 2 versions of Demos #4, #8 and #11.
Project source license changed to Mozilla Public License v2.0 while demo source code and batch files have been placed in the public domain.
Updated documentation.

Significant updates to TPJCustomConsoleApp and TPJConsoleApp classes:
- Several new properties.
- New OnStart event.
- New overloaded version of Execute method.
Added new ReadBytes and WriteBytes methods to TPJPipe.
New PJPipeFilters unit containing classes for safely reading text from pipes and splitting the text into lines. Includes filters for ANSI and Unicode text.
New TPJFileHandle class for assisting in creating files with inheritable handles.
Various new helper routines to ease working with some properties and application error codes.
Added compiler directives that refuse to compile with compilers earlier than Delphi 7.
Some "unsafe" compiler warnings inhibited.
All units now have XMLDoc compatible comments.
Major update to demo projects:
- All demos now work correctly with Unicode Delphis.
- Many revisions to demos to demonstrate new filter and file handle classes.
- Two new demos.
- "Echoer" helper program now has option output Unicode text.
- Some changes to organisation and configuration of demo projects' config and project files.
- New test ANSI text file (extract from "Moby Dick").
User guide removed from project since documentation now in online wiki.
Internet short-cut to documentation wiki renamed.
Updated other documentation files.

Fixed problem with programs failing to execute when compiled with Unicode versions of Delphi due to strange "feature" of Unicode version of Windows CreateProcess API function.
Fixed similar Unicode CreateProcess problem in demo #1.
Switched off unsafe code warnings in PJConsoleApp.pas and PJPipe.pas.
Updated user guide to note that demos #7, #8 & #9 do not work with Unicode versions of Delphi.
Updated other documentation.
