Replacing `$this->version` by the new class constant
Make WP_LANG_DIR constant safer

We assume that someone defining WP_LANG_DIR will do so without a trailing slash, since we then add our own before adding in the rest of the path to the .mo file.

This change gets removes that assumption by removing our own slash from the string, and wrapping WP_LANG_DIR in trailingslashit() instead.

Make WP_LANG_DIR constant safer
Change default capability to 'manage_options'

I am not sure if it's a good idea to use 'read' here, as more people will use the plugins page for options that subscribers... should never see.
I am not blaming you, it was me not paying attention but after migrating my plugin to this awesome boilerplate it ended up on WP.org with 'read' for the entire options page and people are now complaining ;)
