xyscan-4.50-bp154.1.54

- update to 4.5.0 (4.50):
  Most important change is probably the update of the error bar scan mechanism.
  It is now possible to scan several x and y-errors (e.g. stat. and sys.
  uncertainties) in one scan.
  It now has a multi-lingual interface (French and German), although the
  documentation remains available in English only.
  Improvements were made to make full use of screens with a pixel device ratios >
  1 (most modern high-resolution screens).
  The status bar on the bottom now features an additional coordinate display on
  the right.
  A Significant Digits command was added to the Edit menu that allows to modify
  the precision of the displayed coordinates and distances. This also affects the
  numbers saved in a file (or ROOT macro).
  CSV was added as a third possible format for saving scanned data. This allows
  to import the data into spreadsheet applications such as Excel and Numbers.
  A new experimental histogram display was added that shows the grayscale density
  around the cursor. In certain cases this might help to place markers or scan
  points more accurately.
  The format of the data table can now be toggled between stretched and resized
  to content and the alignment of the numbers can be toggled between left, right,
  and center.
