Nvim-tree.lua: Do not reset tree width when opening a document

[kristijanhusak]

Today I was working with some nested folders, where I had to increase the width of the tree window to see full name of the file. Once the file is opened (or previewed), tree size goes back to the default size, which is really annoying when you have to preview multiple things.

Ok, I found a setting in code that is not documented, that does exactly this.

let g:lua_tree_width_allow_resize = v:true

I guess we could just add it to docs.

was added this week, i'll update the docs soon

Also note that it will not work if it's set to 1, so I guess we should either emphasize that in the docs, or make it work for both true and 1.

[kyazdani42]

it should work both for true and 1. I'll fix that altogether
