Allow users to pin custom NCJ templates

[psyrus]

Description
As I have finally got custom batch images working with SES, it necessitated the use of custom templates. I have noticed that it is quite inconvenient to have to re-select the JSON file every time I want to run my custom Maya / Arnold template, and it would be nice to be able to pin templates into the "Local Templates" screen.

There is a lot of wasted space there so having a few tiles with the JSON file's name displayed (or if you're feeling fancy, maybe add another templateMetadata field like "templateName" that we could display the name in addition to the description) would be a plus to the UX, in my opinion.

Of course there is already the "Recent" list of templates that have been used, however it has a max length of 10 and keeps all the data pre-populated which can be a negative point.

I was thinking about something like this:

Edit: Perhaps the ability to even choose to pin the templates on the main Gallery page could be useful.

Dave and I were talking about this today. This is a great idea and could be part of a wider re-org of the Gallery applications now that we are getting quite a lot of templates and the number is increasing all the time.

In the main Gallery page, it would be good to be able to separate out the full list of applications and templates, and those which i use often. Maybe an "All" and "Favorites" tabs. Where i have the ability to not just select the 3ds Max application as a favorite, but the "Render Max with V-Ray on CPU" specific template. That would be in the favorite tab under a Max Icon.

It would be nice to be able to change the way that the recent templates are displayed and also have the ability to clear the list. Potentially having 3 tabs: "All", "Favorites", and "Recent"

This UI is getting completely redesigned into a user library. #1697
This isn't the exactly the same as pinning some templates but I believe this should do a better job in general.
