Title: Allow customizing individual concealing characters

The `g:javascript_conceal` boolean option is replaced by multiple `g:javascript_conceal_*` char options to allow customizing individual concealing characters.

I only want to conceal the common `function` and `return` keywords with custom concealing chars instead of the default one, but it wasn't possible before since `g:javascript_conceal` is a wholesale.

With this change, I can do so by adding the following in my `.vimrc`:

```vim
let g:javascript_conceal_function = "λ"
let g:javascript_conceal_return = "↩"
```
