Wireshark-dev: [Wireshark-dev] [patch] Lua plugin fixes

Hi,
I made some improvements to the Lua plugin:
- Makefile.am fix: elua_register.h generation + checking serialized
- ProtoField.new(..) parameter parsing fix and changes
- enabling gui_enabled() function in Lua (typo fix, thanks to Tamas Regos)

Regards,
Balint
