Fix the typings

[ocket8888]

A summary of what I did (not everything was necessary):

• Angular properties not imported
• Dynamically adding properties that don't need to be accessed in the template
• Namespace types not imported
• Namespace not necessary
• scope.selected set dynamically but value never read
• implicit any-typed parameter in click handler
• click handler JSDoc not bound to any visible symbol - removed
• parameter to collapseRecurse typed as boolean | null instead of optional
• unused parameter to closeSelect
• fuzzy match loops over own properties of string primitive (which typescript doesn't like but appears to work fine in reality) switched to collection loop using of
• evt parameter of collapse has implicit any type
• incomplete description on checkFilters
• simplify scope.$watch callback
• changed a bunch of const funcName = function() {... to function funcName() {... or fat-arrow functions

oh and one last thing you may not have noticed not a big deal but

scope used to have an implicit any, which is why you could access things willy-nilly. Everything is now strongly typed.

I couldn't get importing the namespace to work, so I quickly gave up. It's already module-scoped anyway; since you have to access it as an import the namespace doesn't do anything but get in the way imo.
