nextLineInputFlagWon't Always Be True On Mouse Clicks

[breadnone]

Description

Currently the DialogInput will always set nextlineinputflag to true when clicking mouse multiple times even if there's no writing activity on screen, thus making the next Say auto-completed. Even mouse clicks when there's menu choices will trigger the next Say to be auto-completed.

What is the current behavior?

Every mouse clicks will set nextlineinputflag to true

What is the new behavior?

Add condition to SetNextLineFlag so it won't always be true on button presses when there's no writing activity on screen or when the text is already completed.

Other information

Previous, this auto-complete bug is all over my game. It also gets triggered when there's menu choices. So far, I've not encountered that glaring issue anymore with this patch.

Note: It works for my game, but still needs further testing!

Edit: I could not reproduce the issue with text automatically completed after clicking the button on menu choices. Probably fixed?
