Support Go Mod

[sagadsalem]

hi
I get a new aah project instance and run go mod init to add Go Module to the project after I run aah run
I get

---------------------------------------------------------------
                       aah framework v
---------------------------------------------------------------
# Report improvements/bugs at https://aahframework.org/issues #

FATAL Given import path '' does not exist


go: finding module for package aahframework.org/aah.v0
go: found aahframework.org/aah.v0 in aahframework.org/aah.v0 v0.12.5
go: aahframework.org/aah.v0: aahframework.org/aah.v0@v0.12.5: parsing go.mod:
	module declares its path as: aahframe.work
	        but was required as: aahframework.org/aah.v0
