Bugfix: Error using variable in structure handling

• The standard structure handling widgets and methods had an error is the approach was a variable rather than one of the choices.

Enhancements to line graphs

• Added multiple axes to line graphs.
• Updated to correct version of plotly. 'latest' is actually not.

Updating standard parameters for systems and configurations

• Cleaned up and add to the standard parameters used for naming system and configurations. 'title' refers to the title in the file, if it exists.

Allows capital letters in variables and columns for results

• Allows capital letters for the variables, column names, etc. that results are stored in. For example, 'T', 'P', and 'V'.

Added support for using local data files.

• Added support in the Flowchart and Node classes for using local data files for e.g. forcefields. This allows the user to specify a local file, which is copied to the working directory of the job.
• Also added a flag to both the Flowchart and Node classes indicating that the job is running in the JobServer rather than command-line.
