[Bugfix] Bug fixed at BubbleView&BUnitLineManager

0. BubbleView had line_not_generated BUG. Misuse of if-statement.
1. BUnitLineManager had bug game overs, app died. Misuse of hot-wiring.

[TODO]
BUnitLineManager now has lineLimit, which determines gameover.
This should be handled without hot-wiring.(Use AppOption const instead)
