Send data to openssl pipe via communicate instead of stdin.write

[eddiejessup]

Recently a big file that I encrypt using this plugin started breaking Sublime Text: it froze when I entered my password. Looking into it, it was the line openssl.stdin.write( data.encode("utf-8") ) that was the issue. From the subprocess docs,

Warning Use communicate() rather than stdin.write, .stdout.read or .stderr.read to avoid deadlocks due to any of the other OS pipe buffers filling up and blocking the child process.

I think this is what was happening, as it's only big files that break it. I moved the data input to the communicate line, and now it works for me.

I only realised the solution was so simple just now, and before realising that I made a fork of your plugin using the PyCrypto module that went on the package manager today! I'm not sure whether to keep it since it isn't really needed any more.

Awesome, thanks @eddiejessup. I never tried running the plugin on anything very large, good find!
