v2.5.0-beta.1

This is an beta release of version 2.5. Version 2.5 is a major rewrite of the code base. This version should be used carefully as it may contain bugs.

Major Updates Include:

• Removal of QtWebkit and replacement with QtWebEngine to match plan for long term Qt development since QtWebkit will no longer be supported
• Removal of HighCharts javascript plotting and replacement with QtCharts. QtCharts should be able to handle much more data without slowing the code down and causing crashes
• Minor updates to the user interface that include allowing user to select hours/minutes/seconds/days to be added to shift a time series input file
• Added some default colors to be selected when adding time series data to the program
