media/lua -> media/scripts
octascript: get rid of the op_to_lua fuckery
octascript: constant folding and specific codegen for bit ops
octascript: typeof expression
octascript: begin runtime work
octascript: move type into runtime
octascript: put import implementation into runtime
octascript: add support for "try" expression/statement

This expression/statement is meant for error handling. It does pretty much what
pcall in Lua does, but with nicer syntax. It's available as both statement and
expression, and has variants with and without handler (i.e. pcall/xpcall)
octascript: support for "raise" statement

Pretty much replaces standard Lua "error" function. Takes any expression
and allows specification of level via special syntax.
remove all usages of pcall and error
octascript: null value support
octascript: better not operator semantics

The not operator now gets false on null cdata.
octascript: null now doesn't equal none
octascript: none -> undef for better clarity
octascript: tostring(undef) now returns "undef" rather than "nil"
octascript: "typeof undef" now returns "undef" rather than "nil"
octascript: begin migration to new standard library
octascript: fix bytecode gen bug in "from x import y" statement + stdlib changes
octascript: fix a similar bytecode gen bug in LocalMemberDeclaration (var a, b, c in d)
some more stdlib changes
