fpcres DIALOG support
## Summary
Attached RC doesn't compile with fpcres (release, trunk), but does with windres or brcc32.
The problem line is the DIALOG one. I'm not 100% sure this is a bug in the DIALOG parsing (modifiers like MOVEABLE PURE LOADONCALL DISCARDABLE before coordinates instead of after?) or totally missing DIALOG support, since I can't find productions for the _DIALOG(EX) except for the basic keyword that is in the lexer.
## System Information
win32, but I assume any.
## Steps to reproduce
fpcres -of res defbox.rc -o defbox.res
## Example Project
attached rc + ico
## What is the current bug behavior?
```
#MAIN.RC(2:50): at "0": syntax error
200 DIALOG MOVEABLE PURE LOADONCALL DISCARDABLE 0,0,403,237
^
Error: EResourceReaderUnexpectedEndOfStreamException
```
