Introduce new settings to include/exclude the miscellaneous fees when generating penalty

[RoiJS]

On issue #52, a setting was introduced to specify the due date for miscellaneous fees, either same with the utility bills or rental fees. There is a condition that if the miscellaneous due date is the same with the rental fees then include the miscellaneous fees when checking for penalty. There might be a scenario where user would not want to include the miscellaneous fees when checking for penalty. To resolve this, we are going to introduce new setting on terms level that will include/exclude the miscellaneous fees when checking for penalty.

TODO:

• On term details page particularly on Miscellaneous Settings panel, add new setting called "Include in Checking and Calculating Penalty". Make this setting only available if the Miscellaneous Due Date is set to same with the rental fees. If Miscellaneous Due Date is set to same with the rental fees and the new setting is activated then make sure to include the miscellaneous fees when checking for penalty. And if the penalty value type setting is set to Percentage, make sure to get the penalty percentage value on the sum of rental and miscellaneous fees.
• Add new Miscellaneous Settings Panel on Terms Details page.
• Update unit tests
• Update online documentation

The new setting is now implemented. Necessary changes for both unit tests and online documentation have already been implemented as well. Moving this issue to close now.
