Adds "StartsWith" / "EndsWith" options to _ArraySearch / _ArrayFindAll

[anonymous]

_ArraySearch and _ArrayFindAll allow partial search with $iCompare = 1, how about adding StartsWith and EndsWith search option too?

Not important, just a convenient option, making theses functions a little bit more powerful, although a bit slow.

Without it, we can still use simple loop to perform such search, or using regex by escaping the search string and inserting a ^ or $, no big deal...
