What´s New 1.0b2
with much help from powtrix, here comes the Linux/X11 build.

* added combobox for bios, ctrlr and effect options
* fixed mame detection for Linux build

* Linux build [powtrix]
* added Brazilian translation [powtrix]
* click image to rotate snapshot tabs
* added menu to switch GUI styles
* added path selector for history.dat, mameinfo.dat, story.dat


Notes for Linux build:


* make sure the user have sufficient privilege to read/write GUI settings directory "$HOME/.mamepgui" and SDLMAME config directory "$HOME/.mame" or "etc/sdlmame"
* there are still some Linux-specific bugs, sometimes you have to restart FE after F5 auditing, and you can´t sort the game list.
* this FE will be open source in a few releases.
