Allow typing a toot while an image uploads (#1429)

Browse source 
This patch stops disabling the toot text field when an image is uploading. Instead, you can type to your heart's content and when the image uploads it'll append the image URL, and restore the position of your cursor to wherever it was in the toot text just prior. Effectively, the image URL is appended to the toot, and typing is not interrupted at all! ✨
