Legend Option for Bar/Row Charts & Bugfixes

Features:

• Bar and Row Charts now also come with a legend option in the settings, that can be enabled or disabled by default.
• You can now directly change the granularity of the Time Series widget from the dashboard view by simply selecting a different one (day, week, month, quarter, year) in the upper right corner.

Improvements:

• JIRA custom field date is now imported as a da and not a category, so it can be used in timeline charts
• Removing the required pivot-field from a widget now prompts the user to select a pivot field instead of the red error message.
• Fixed a bug that caused the Quota widget to display "time frame in past" when no time frame selected.
• Improved the delete-confirmation modal for widgets. It is now shown directly within the selected widget.
• The data type of widget groups can now be deleted again.
• additional minor fixes
