Restrict implementations based on future financed costs

[nbintertech]

Need to modify checkCanImplement so that we account for the next year's financing expenses and:

1. restrict user from implementing project if current financing year-to-year puts them in the whole
2. AND/OR give user pop up warning advising they cannot afford any more projects for the year.

With 2 need to know generally how we want to handle negative finances scenarios. Prevent them from happening in any scenario? keep the balance rolling and let user try to make it up/fail?

#177 Tie in?

Same with 177 - with changing to only 1 or 2 financing projects/year and moving more towards not as much energy savings, this is less important
