Merge branch 'release/2.14.2'

This release fixes the following tickets:
* #62: Instead of or in addition to the Restore Default Zoom button, add
Full Zoom Out button.
* #64: Load multiple trace files and enable the possibility to view
signals from different files in a single window.
* partial #66: key shortcuts for actions like zoom in/out, go to
next/prev event etc
* #70: add full zoom and zoom between markers (once we had markers)
* #75: marker is often hiding events underneath for highlighting and
getting transaction details
* #82: Implement help for keyboard shortcuts

+   - Content may be structured and packaged into modules to facilitate delivering,\n\
+     extending, and upgrading the Content. Typical modules may include plug-ins ("Plug-ins"),\n\
+     plug-in fragments ("Fragments"), and features ("Features").\n\
+   - Each Plug-in or Fragment may be packaged as a sub-directory or JAR (Java? ARchive)\n\
+     in a directory named "plugins".\n\
+   - A Feature is a bundle of one or more Plug-ins and/or Fragments and associated material.\n\
+     Each Feature may be packaged as a sub-directory in a directory named "features".\n\
+     Within a Feature, files named "feature.xml" may contain a list of the names and version\n\
+     numbers of the Plug-ins and/or Fragments associated with that Feature.\n\
+   - Features may also include other Features ("Included Features"). Within a Feature, files\n\

+\n\
+   - The top-level (root) directory\n\
+   - Plug-in and Fragment directories\n\
+   - Inside Plug-ins and Fragments packaged as JARs\n\
+   - Sub-directories of the directory named "src" of certain Plug-ins\n\
+   - Feature directories\n\
+\n\
+Note: if a Feature made available by the Eclipse Foundation is installed using the\n\
+Eclipse Update Manager, you must agree to a license ("Feature Update\n\
+License") during the installation process. If the Feature contains\n\
+Included Features, the Feature Update License should either provide you\n\
+with the terms and conditions governing the Included Features or inform\n\
+you where you can locate them. Feature Update Licenses may be found in\n\
+the "license" property of files named "feature.properties". Such Abouts,\n\
