FPC recompilation automation

When you want to change something in FPC, you will have to repeat several commands many times to rebuild FPC and test your changes. Here is a script to automate this process.

FPC rebuilding script for Windows

Save the following script as rebuild-trunk.bat. Tested on Windows 10 x64, FPC 3.3.1 with 3.2.2 bootstrap, and 32 bit FPCUPDELUXE 1.8.2u.
