+ If there is scrolling then force the scrollbars to always appear.
+ Align contents of the dialog with the title.
+ Change "Network SSID" to "Network name".
+ Added wifi_* styles to other style xml files so that Wi-Fi hotspot dialogs are visible on tablets.
+ Move layout_width/height from res/layout/{wifi_dialog.xml, wifi_dialog_row.xml} from style into the xml file.

Use arrays.xml to store translations for enumerations;
avoid race conditions happened when pop up menu or dialog;
avoid saving configurations with networks disabled;
use the same layout for all the dialogs;
support editing EAP networks;
only unlock keystore before connecting;
and many bug fixes I cannot remember.
The number of lines in the new code is about 1/3 of the old one,
and it improves the readability a lot!
