* First pass at optimizing ale to autoload First off, the structure/function names should be revised a bit, but I will wait for @w0rp's input before unifying the naming style. Second off, the docs probably need some more work, I just did some simple find-and-replace work. With that said, this pull brings major performance gains for ale. On my slowest system, fully loading ale and all its code takes around 150ms. I have moved all of ale's autoload-able code to autoload/, and in addition, implemented lazy-loading of linters. This brings load time on that same system down to 5ms. The only downside of lazy loading is that `g:ale_linters` cannot be changed at runtime; however, it also speeds up performance at runtime by simplfying the logic greatly. Please let me know what you think! Closes #59 * Address Travis/Vint errors For some reason, ale isn't running vint for me... * Incorporate feedback, make fixes Lazy-loading logic is much improved. * Add header comments; remove incorrect workaround * Remove unneeded plugin guards * Fix lazy-loading linter logic Set the wrong variable.... * Fix capitialization
