Stipend

[Lyisus]

Fixes issue #179 where Stipend was hard coded in several places in the application. This PR will create a new field in the parameters table of the database called "stipend" where it will hold the stipend amount to be used wherever it is needed across the application as well as easier management in case it needs to be updated in the future. A new field in the setParameters page was created in order to facilitate the modification of the stipend in the future. The budget.html file has a minor refactor so that the textareas for Faculty Stipend are created with different placeholders than those in the config.yaml file, as they are created by looping through the budget elements in that file.

How to test:

• In the setParameters page, create and modify new parameters with different stipend amounts
• In the budget page, the first set of fields for Faculty Stipend will display the amount that's set for the current year in the parameters table
