Let all editbox support drag and drop files and texts

[macman]

@Kevin

Add multi paragraph text, achieved by dragging?

Now The text I drag the second time will replace the text I drag the first time

It will be more convenient if can drag and drop some texts for many times

In addition, now press enter in the edit box to create a new line, which will close the dialog box
