#185 flexible split features

[masrin]

current version up to 1.6d(guessing) is not flexible enough and at left side is fix to 1 unit only. for example, A stock got split or bonus from 3 to 4. current version at left side is fix to 1 and we need to key in right side which is 1.333, which the real result if stock is 1000 unit, it will become 1333, and 3000 will become 4000. if we use 1.333, the result is totally not accurate.
I suggest left side should be able to key in with 3 and right side with 4, the result should be calculate as (current total share) x( 4(rightside) div 3(leftside)) will give more accurate to bursa malaysia.
