Make config universal

[myarcana]

I had

require("telescope").setup {
    extensions = {
        project = {
            hidden_files = true, -- default: false
            display_type = 'full', -- default is 'minimal' which only shows name but not path
            hide_workspace = true, -- default: false
        },
    },

In my vimrc for the longest time without noticing my settings weren't having any effects.

In taking a look at @akkaargh's comment in #165, I noticed that there were two types of settings for this plugin: picker-time settings and setup-time settings.

Actually, it seems like all options make sense to be able to apply both at setup time and at picker-open time, so I've merged them.

After this PR, my config will start to work as I had originally expected it to.

Sorry @myarcana I missed this one, and now there are conflicts. If you're able to resolve the conflicts - run it locally without issues, I will re-review and merge. Thanks
