UI: Improve processing time of vogleditor_apicalltreeitem by pre-calculating the local row index
* This value will have to get updated if new rows (API calls) can be added / removed, which may undo this optimization,
but when investigating a slowness during searching, the code was often found in this function.
UI: Fix issue #20: Search in the editor really slow
* Instead of selecting all the rows which match the search string,
  the tree view now highlights those rows which match and are visible.
* If the user presses [enter], the first matching row (if one exists) will
  be scrolled into view and selected.
* Continually pressing enter will cycle through each match, in the same way
  that clicking the "Next" button works.
* If there are no matching items when the user presses [enter], the background to the search textbox will turn red.
  It will restore to its previous color when the user next edits the text.

Typo?
UI: Fix issue #21: Resizing of vogleditor window is slow depending on trace size
* If the window is only being resized a small amount (within 20%), the timeline will no longer redraw and simply gets stretched.
* When the timeline is redrawn, it will now only draw one timeline item per pixel instead of many sub-pixel items.
* Fixed an issue that caused 0-duration items from being scaled to 1 instead of the horizontal scale value (which should be the minimum amount of time needed to appear as a single pixel). This greatly reduced the number of items being drawn.
* Fixed deletion of timeline item children.

* These improvements reduced the number of drawn items in one particular trace file from ~5.9 million, down to ~1250 in the default window size. When I stretched the editor across two monitors (giving the timeline more pixels to draw into) this increased to ~4500 items - both very reasonable numbers.
