fix the make-confwiz-match-installer-size changes, to eliminate some weird
layout/rendering bugs. also tweaked the layout slightly to add space between
the warning label and the newsletter subscribe checkbox.
this will write an arbitrary number of config files, instead of being restricted
to just the introducer.furl, based on the response of the php backend.
the get_config is passed username/password
Previously, once the node itself was launched, the UI event loop was no longer
running. This meant that the app would sit around seemingly 'wedged' and being
reported as 'Not Responding' by the os.
This chnages that by actually implementing a wxPython gui which is left running
while the reactor, and the node within it, is launched in another thread.
Beyond 'quit' -> reactor.stop, there are no interactions between the threads.
The ui provides 'open web root' and 'open account page' actions, both in the
file menu, and in the (right click) dock icon menu.
Something weird in the handling of wxpython's per-frame menubar stuff seems to
mean that the menu bar only displays the file menu and about etc (i.e. the items
from the wx menubar) if the focus changes from and back to the app while the
frame the menubar belongs to is displayed. Hence a splash frame comes up at
startup to provide an opportunity.
It also seems that, in the case that the file menu is not available, that one
can induce it to reappear by choosing 'about' from the dock menu, and then
closing the about window.
this moves some of the code common to both windows and mac builds into the
allmydata module hierarchy, and cleans up the windows and mac build directories
to import the code from there.
