(editing existing comments is not yet implemented)

CSS:
colors.css: made an extra ruleset for the colors, now all elements - with class dark or light - in an element - with class event type and active - will also push the color through.
comment.css: corrected text wrapping and placeholder.
scenario.css: fixed unwanted extra space in height and inserted classes for placeholder.

JS:
CommentMain.js: removed templateComment.
CommentManager.js:
 - replaced templateComment with currTemplate: currTemplate will now be set when starting editing a comment so the correct template (in the right scenario) will be selected.
 - refined the on click handler for clicking comments.
 - shortened animation durations.
 - finishEdit is now the method to end editing, a bool determines if the changes apply or not. TODO: alert on empty input value.
 - removed createComment.

ScenarioManager.js:
 - removed templateComment.
 - moved scenarioWrapper on click and corrected insertBefore.
 - small visual change: change text of p in scenario from "Add New" to "New".
 - added methods to switch visibility of placeholder and scenario content.

Templates:
main.css: new file for the generic styling in the templates.
scenario.html: added placeholder.
