show newly connected contacts in green and contacts that have just disconnected in red before removing them. Presentation/colors have to be improved, but the principle is there (to be tested).

now when we do make, it compiles py files to pyo and make install install pyo files instead of py files

do show_all implicitly everywhere [glade windows visible=False]. I did this so when show_all() it will be shown then [after connect and stuff], and not when being parsed

reorder functions so that they are in the order in which they appear in the window

print an error when we try to connect an inexisting server instead of crash

try to fix ticket 148. has some problems: it wont display the accounts with erros in the accounts window. Only after you close it and open it again
