refactoring phase

heap of renamings (English mistakes ), bus-icon added (print screen from
their android schedule app), button became toggle button, checkboxes for
indicates which provider currently used, added input field for ip (now
it simply there..), corrected logic getting data from providers (network
points are not obtained when the gps works), correct bugs (infinite loop
when internet disabled, etc), get only status of post query (not read an
empty answer)
