Donate more SVG icons, and install more duplicates

[eirikbakke]

This PR adds scalable SVG versions of a few more NetBeans icons, for Retina/HiDPI screens, originally drawn for the Ultorg project. Some of the existing icons are also copied to new locations that were discovered to be visual duplicates of the same original bitmap images. Part of NETBEANS-2617.

See this HTML page table for a complete summary of icons in the NetBeans codebase as of today and this PR, with identified duplicates and mappings to SVG files.

Details:

• Add new SVG icons:
  • Action icons for Cut, Copy, Paste, Notifications, Output, and Properties.
  • Speech bubble variations used to display notifications in the toolbar.
  • error/aborted/info/ok/question icons that are used in various places.
  • Additional icons included: lightbulb, globe, newFolder, configBadge8x8, print, hierarchy, restart, runProject
• Regenerate and refresh all SVG icons that came from the same Illustrator file; some of these received minor tweaks since they were last committed.
• For each of the currently drawn SVG icons, do a thorough search among existing GIF and PNG icons to find either identical or visual duplicates, and copy in the corresponding SVG icon in each place.

The following composite of screenshots shows a few examples of new SVG icons:

This PR adds or touches SVG files only, and includes no code changes. The Adobe Illustrator file that was used to generate the SVG files will be committed in a separate PR (here), along with the script that was used to find duplicates, copy the files to the right locations, and generate the HTML page summary.
