Update SendGridEmail.groovy

Avoid limiting attachments having to be a file in FS, they could be an outputstream generated from the app.

Hi @xavs - thanks for this.

Any chance of getting a quick test written for this as well? The codebase is well tested and I don't want that to change.

I just created a 1.x branch to allow users contributions to the Grails 2.x version of the plugin. Anyway, a test for this will be much appreciate it.

Hey guys, where are the tests in the repo?
I did use this fix for a while, it does work, but that doesn't mean there could be some collateral damage. I'm not having much spare time these days, but I'll try to revise this soon

Hi @xavs

Under the 1.x branch. You can find them here: https://github.com/desirable-objects/grails-sendgrid/tree/1.x/test

The current master branch contains the newer version for Grails 3.x. The branch 1.x is for the version that works for Grails 1.3.1 > +
