[Inkscape-translator] inconsistency - probably missing colon

In these group of strings I suspect that a colon should be added for these strings:

"Display Mode Cycle" => "Display Mode: Cycle" "Display Mode Toggle" => "Display Mode: Toggle"

This because:

#: ../src/actions/actions-canvas-mode.cpp:256 msgid "Display Mode: Normal" msgstr ""

...

#: ../src/actions/actions-canvas-mode.cpp:257 msgid "Display Mode: Outline" msgstr ""

...

#: ../src/actions/actions-canvas-mode.cpp:258 msgid "Display Mode: No Filters" msgstr ""

...

#: ../src/actions/actions-canvas-mode.cpp:259 msgid "Display Mode: Hairlines" msgstr ""

...

#: ../src/actions/actions-canvas-mode.cpp:260 msgid "Display Mode Cycle" msgstr ""

...

#: ../src/actions/actions-canvas-mode.cpp:261 msgid "Display Mode Toggle" msgstr ""
