Show size of e-mail being composed.

I believe mail providers typically place limits on the sizes of e-mails that are sent. Gmail’s is 25MB, for example.

I think eM Client should provide a way for users to see the sizes of e-mails they’re composing. This make it easier to bring e-mails under the size limits. Without this, users have to guess or manually go and add up the images’ sizes.

One way to do this is to show the size in a status bar.
