spyder meta.yaml dependencies

[davidslac]

I have had some trouble installing spyder into existing conda environments. I seem to be able to have worked around this by updating the packages that spyder depends on, I think all that really mattered was qt, namely going from 4.8.5 to 4.8.7. It suggests to me that the meta.yaml for spyder is not resctrictive enough on the dependencies.

For instance, the py35 error was

line 260, in set_editor
    from spyderlib.qt.QtWebKit import QWebView
  File "...//python3.5/site-packages/spyderlib/qt/QtWebKit.py", line 10, in <module>
    from PyQt4.QtWebKit import *  # analysis:ignore
ImportError: ...//python3.5/site-packages/PyQt4/QtNetwork.so: undefined symbol: _ZTI10QSslSocket

Ok, I'll update it to the latest Qt :-)
