Changed: The []= operator for strings and sequences is now capable of splicing

Added: PNimrodNode.lineinfo for better error messages from macros
Added: seq.splice
For easier use from templates and macros, except stament now supports
the list of exception types to be supplied in nkBraket node (array literal).

Added string interpolation helper routines in parserutils
Added a proof-of-concept string interpolation user-land macros (currently, only as a test case):
the interpolated expression could either be transformed to
concat("literal string ", $(interpolated), " end") or
"literal string $1 end" % [$(interpolated)]
Added a very initial definition of Optional[T] generic type
A new overload of ParseIdent was added in hope to get around the fact that the
old one doesn't work correctly in macros, but the problem persists.

proc parseExpr*(s: string) : expr {.magic: "ParseExprToAst".}
## Compiles the passed string to its AST representation
## Expects a single expression
proc parseStmt*(s: string) : stmt {.magic: "ParseStmtToAst".}
## Compiles the passed string to its AST representation
## Expects one or more statements
proc getAst*(macroOrTemplate: expr): expr {.magic: "ExpandMacroToAst".}
## Obtains the AST nodes returned from a macro or template invocation
## example:
## macro FooMacro() =
## var ast = getAst(BarTemplate())
Handling of the node.toYaml magic moved to the evaluation engine.
