Functional v0.6.0

Changes

• list.find and list.findInRange now return the index of the found item in the list as a second return value (thanks @Myaamori)
• string.split: now takes an additional limit parameter to specify the maximum number of split operations (thanks @Myaamori)"

Fixes

• util.assTimecode2ms: fixed a null-reference exception due to local tonumber reference being reassigned to nil (thanks @Myaamori)
