Improve the logs system max limit feature to reduce more memory usage

[BenYeeHua]

I just think that, if Process Lasso can let the user set the limit of the logs that will showing on the UI, it will be good.
So the user can also reduce the limit of the logs that will store on the memory/RAM too, even it is not too much.
For user that has many RAM, they can also increase the limit of the logs as they want.
