Dataset trans2

[100pah]

Enhance data-transform:

• rename parse to parser. (break from 5.0.0-alpha.1)
• Make value comparable (in filter transform and sort transform) accurate and disambiguate in "numeric-like string" and other non-number types.
• Add parser "number"
• Add config "incomparable" to sort transform. The value can be 'min' or 'max', means that the value that not comparable will be trade as min value or max value.
• Modify the definition of util/number.js#isNumeric a little (exclude '0x11' and include Infinity). (break but effect little).

test case:

• test/data-transform.html
• test/ut/spec/data/helper/dataValueHelper.js
• test/ut/spec/util/number.js
