Fixed require statements

[Trial97]

The require statements should be dynamic in order to place this project in another folder other than the root config folder

Thank you for your work. Please see my review.

Before merging, can please you ensure that you tested every widget, layout and utility?

Maybe you can help me with #527 as well.

Thanks for the review. I reverted the change. Regarding testing everything it will take me some time as I just started learning lua and awesomewm. As regards #527 can you elaborate? It is enough for the files to only have the require statement in them? e.g.lain-test-quake.lua

local lain      = require('extra.lain')
return lain.util.quake({
    app = 'kitty',
    name = "QuakeDD",
    argname = "--name %s",
    followtag = true,
    settings = function(c)  ...    end
    extra = '',
    border = 1,
    visible = false,
    overlap = false,
    screen = awful.screen.focused(),
    height = 0.25,
    width = 1,
    vert = "top",
    horiz = "left"
})

Unfortunately not, we need to call in each of them all possible functions/widgets with all possible arguments to see if anything breaks in a new commit.

The reason why I mentioned #527 is that if we solve that one, we can also check the validity of this PR.

Ok, a small update to this:

• added a first set of tests(not all files but maybe)
• fixed requires to work with both tests and also in an awesome config

Let me know if there are some changes that need to be done regarding tests(if not I will continue adding them in the same manner if I have time)

docs for the future :D
