Allow custom labels for details objects

[emmorris]

We tried to use the following settings in RhoMAP, but got [object Object] when we tried to view the details in the data listing view. Our documentation says that we can customize the details objects, so we should update the code to allow that kind of setting.

{
variables: {
details:
[
{
'value_col': 'AESER',
'label': 'Serious Snape'
},
{
'value_col': 'AESEV',
'label': 'Severus Snape'
}
],
filters:
[

{
'value_col': 'AESER',
'label': 'Ser',
'type':'event',
'start':[]
},
{
'value_col': 'AESEV',
'label': 'Sev',
'type':'event',
'start':[]
},
{
'value_col': 'AEREL',
'label': 'Rel',
'type':'event',
'start':[]
}
]
}
}

Note: We should able to get the listing to only show two columns by specifying
details:
[
'AESER',
'AESEV'
],

Test Notes:

1. Ensure details listing appears as normal before adding anything.
2. Add a details object, like in the example above, that has columns with and without a label and ensure that they show up by themselves and with the proper label when you view the details listing
