Make libpinyin setup could response build config

[qiangzhao]

Hi @epico:
I found that currently ibus-libpinyin setup don't response for compile options, (eg: --disable-lua-extension, --disable-english-input-mode). What ever they are enabled or not they will show in the user data frame:

So I change the configure.ac, setup/config.h.in to pass these values to ibus-libpinyin setup;

While ibus-libpinyin setup use grid to GtkGrid to show these check buttons, so when I try to hide related button, there will have one or more blanks in the grid:

So I change the main2.py to dynamically attach buttons to the grid to make display more clean and tidy

Modifiedsetup/Makefile.am a little: Make it could drop generated config.py when make clean :-)

With the respect of your great previous work, other places are the same as before.

Please take a review when you have time. Thank you so much!
