+1, failed operations on segments should not trigger graph redraws.

I have tested the new feature a bit (I have looked also on the code, but 
I do not speak JavaScript very well) and so far I have found these issues:

1.) If you first setup topology w/ domain level 0 and try to render 
topology graph, you are correctly informed that managed topology is 
available on domain level 1 only. IF you raise your domainlevel and 
click refresh, you get the same error message, probably because the 
request to get domainlevel is sent only in the beginning of session. You 
have to logout and then login back to see the graph.

2.) If I add a new segment using Add dialog and clicking 'Add & edit' 
button, I get the following error:

"""
IPA Error 3007: RequirementError

'topologysuffixcn' is required
"""

However the segment is created normally. I guess that there is some bug 
when viewing the segment immediately after creation.

3.) The key with suffix colors should be more descriptive. I would like 
to propose the following format:

"""
Color coding of segments by suffix:
{suffix_name} ({suffix_dn})
e.g.
ipaca (o=ipaca)
realm (dc=ipa,dc=test)
"""

4.) It would be nice if the graph canvas could be dynamically resized 
based on the container size, but I am not sure how difficult it is to 
implement it.

(Graphical nitpick: I would change the color of nodes, green does not 
fit very well with the bluish/grey  palette of other WebUI elements)

Otherwise I think that it is a good start and additional features can be 
built on top of this patchset.
