signature

Project: NPanday
Issue Type: Bug

Reporter: John R. Fallows
When building NPanday.Artifact project with Mono on Linux the following error
is presented.
{code}
[INFO]

{code}
This is caused by method signatures with Enum types being reduced to type int
in Mono, and in this specific case it causes a collision with an existing
String.split method signature that really does have an int parameter.
An example of the code causing the error can be found in ArtifactRepository.cs,
line 60:
{code}
String[] tokens = uri.Split("/".ToCharArray(),
StringSplitOptions.RemoveEmptyEntries);
{code}
A simple fix that keeps the precise meaning of the original code but makes the
method signature unambiguous:
{code]
String[] tokens = uri.Split("/".ToCharArray(), Int32.MaxValue,
StringSplitOptions.RemoveEmptyEntries);
{code}
