Fixed a bug that was causing a crash when a WordDisplayWidget was deleted.
Ctrl+Alt+Q plays the sound for the current line.
Merge branch 'Branch_653c069b1f706964246e9149a40e108142df2acd' into Branch_fb62869deaf2e19ccc95dca5a7489f634fc5f927
Changes to XQuery calls to make it work with Qt 5.
Fixed alignment of ImmutableLabel, since Qt 5 handles that differently.
Merge branch 'EditAfterMerge' into Branch_fb62869deaf2e19ccc95dca5a7489f634fc5f927

Completed the merge-then-edit feature, and a couple of other misc fixes.
Code cleanup and a shortcut key.
Removed morphological analysis tab (temporary measure until I can get the different views working.)
The "Views" feature has been added, and seems to work for full interlinear displays. Quick views aren't supported yet.
Set matching following gloss items to the interpretation of the current gloss item.
Replace baseline text following gloss items when the baseline text matches current.
Fixed the function for duplicating an interpretation (all text forms and glosses are now duplicated), and put a menu command in a more intuitive place.
Deleted a class that was evidently never used.
Eliminated some extraneous concordance calls.
Implemented FlexTextImporter, finally separating the logic for reading flextext files created by Flex and flextext files created by Gloss.
Close the configuration.xml file after reading it.
Serialize text after EAF import (though this still doesn't work entirely correctly).
Error reporting without messing up the HTML formatting.
Proper encoding of strings for XQuery calls.
