v0.18.0 - dd/mm/yyyy

Changes affecting backwards compatibility

• Removed basic2d/basic3d out of the stdlib and into Nimble packages. These packages deprecated however, use the glm, arraymancer, neo or another package.
• Arrays of char cannot be converted to cstring anymore, pointers to arrays of char can! This means $ for arrays can finally exist in system.nim and do the right thing.
• echo now works with strings that contain \0 (the binary zero is not shown) and nil strings are equal to empty strings.
• JSON: Deprecated getBVal, getFNum, and getNum in favour to getBool, getFloat, getBiggestInt. Also getInt procedure was added.
• reExtended is no longer default for the re constructor in the re module.
• The overloading rules changed slightly so that constrained generics are preferred over unconstrained generics. (Bug #6526)
