Subject: [PATCH] enhance: paste text on subject

* for single line text, all text will be pasted in subject text box
* if paste in the middle of subject content, multi-line text will be transformed into single line text by `ReplaceLineEndings(" ")`
* if paste in the end of subject content, multi-line text will be split into two parts.
    - first line will be pasted in the subject box
    - remains will be pasted in the start of description box
