Changelog

   Falcon (0.9.1.2)
  * fixed: Correct parsing of octal number (0 and 7 was out...)
  * fixed: Crash with statements == just numbers, and allowing interactive
           compiler to parse non-stand alone expressions and evaluate them.
  * fixed: A leftover from version 0.8.14 caused tables not to properly mark
           their contents on garbage collection.
  * fixed: More flexible int() and numeric() functions (thanks Kless).
  * minor: Added functions vmModuleName, vmModulePath and vmRelativePath to
           help solving dynamic dependencies.
  * fixed: [DANGER]: Fixed missing GC marking of items in frame stacks (mainly
           self and binding registers). This was in since 0.8.0; it was less
           evident because 0.8 had sender which cached the last minus one
           self objects, saving at least the previous caller, and it was
           unlikely that the nth-2 caller wasn't cached somewhere else in the
           VM.
  * fixed: include() was using a cached pointer variable to create the error
           message; the VM stack may have been (usually is) dirtied, so the
           pointer was invalidated. This could have caused random crashes
           and errors in reporting the failing module name.
  * fixed: Finetuned module loader error reporting (now it indicates the module
           whose dependency wasn't found).
  * fixed: Some functional selectors (any & c) still returned 0 on false and 1
           on true.
  * minor: String.merge() now accepts only an array as parameters, and works
           as String.join() does with its parameters.
  * fixed: Const atoms din't include negative numbers (i.e. negative numbers
           couldn't be used in enum declarations).
  * fixed: Reporting a consistent error when aliasing different modules to the
           same namespace.
  * fxied: Now the VM correctly lets imported undefined symbols not being
           part of namespaces to generate a proper error.

Feathers (0.9.1.2)
  * fixed: In MXML, removed promotion of data nodes when there are
           other sibling nodes.
