Fixes issues #51, #56, and #61.

• Cancel button turned into x in corner
• Save and delete buttons grow to half width
• Notes textarea added
• Add pre-req button styling fixed
• Fixed input styling so adjacent inputs appear as one continuous section
• Pre-req delete button mirrors semester delete button
• Also updated semester wording to term

Looks good!

My recommendations:

• Add a bold heading to the notes field just like how the Name, Department, Number, and the other fields have above them, for consistency sake.
• Make the notes textfield not resizable
• Make the X bigger and aligned with the Edit Course title. I picture it being the same size as the letters in the title

Couple comments/questions:

• As @khanny17 said, bring the x in the top right down to line up with the "Edit Course" at the top. And don't have the text be resizeable, also can we make it a little taller? Like 70px (which I think is 5em, if my calculations with the 14px font is right) so that we can see 3 lines of text at any one point instead of 2?
• Do we want the delete 'x' for prerequisites to change color on hover over the entire prerequisite block? I feel like it is a little strange that it does that. Cause it kinda takes my eye away from the class title I may try to read and make we confused as to why it is active. I think changing color when I hover over the X itself is good enough.
• Is there a max number of prerequisites that we'll allow a user to add? Cause if that number gets a little too big, we'll have a really tall modal. Maybe have it be able to show around 3 at once without needing to scroll. Since I can't imagine a class with more than 3 prerequisites in most cases.

Right now I've fixed/added:

• x coloring for deleting pre-reqs to just on x hover
• Notes header
• Notes fixed height of 3 lines
• Close x is larger and aligned with modal title
• Added some spacing between modal buttons

Haven't touched the number of pre-reqs since I'm not sure about that yet.

Don't worry about the number of prereqs. We can worry about limiting size of plans (including prereq number) later. For now if a user wants to put 50 prereqs, be my guest.
