Updated cad/klayout to 0.24.10
------------------------------
(from: http://klayout.de/development.html)
Version 0.24.10
Release date: 2017-04-01
Features:
    Enhancements: New method CellView#is_dirty? This method indicates
    that a cell view needs saving

    Bugfix: DEF reader was not able to read routing Routed segments
    with vias plus continued wiring were not read. Instead an error
    message was shown saying "Invalid orientation specification"

    Bugfix: Setting "technology-data" configuration property did not
    work Reading or writing the "technology-data" configuration
    property is the only way to access technology data from a
    script. Hence it's important that this property can be set. With
    this patch, "technology-data" can be set to an XML string which
    has the same format than the one stored within the configuration
    file.

    Bugfix: Reader issues with some RVE files The RVE reader could not
    read files with cell names containing hyphens (like "A-B").

    Bugfix: Inplace operators are now working in Python too For
    example "r1 += r2" was not working (r1 and r2 are pya.Region
    objects for example).
