Removed default headers (X-Konflux) from cross-site HTTP requests
kx.type and kx.isType now operate more intuitively

kx.type
- removed 'integer' and 'float' types
* added 'null' type

kx.isType
+ added numeric type checks 'number', 'integer' and 'float', which may also be shortened (be careful checking for 'f', as this will allow for f(unction) aswel
+ added relaxed object type checking by allowing for 'object' aswel as the constructor name (note that constructor names are in act case sensitive)
