src/widget/main_window/design First visible window (with memory leaks)

To display this minimal window, three files and two functions must be
added simultaneously:

- include/widget/h
- src/manager.c
- src/main_window/design.c

main() now contains: g_signal_connect (on_windows_activation);
on_windows_activation () is in src/manager.c and calls
widget_main_window () which is in src/main_window/design.c

NB  The iconic image of E coli drawn by David S. Goodsell in 2009
is reproduced here with permission.

One goal of Gem-graph is to animate such static representations
i.e. use the best anatomy to try to achieve good physiology.
