New Features

• Added support for compiler_options and command_line_arguments.
• Added configuration variables ENABLE_COMPILER_OPTIONS, ALLOWED_LANGUAGES_FOR_COMPILER_OPTIONS and ENABLE_COMMAND_LINE_ARGUMENTS for controlling usage of compiler options and command line arguments.

Security Improvements

• Run compilation process for compiled languages inside sandbox and use values of limit configuration variables for controlling sandbox resources.
• Move application location from /usr/src/api to /api to prevent untrusted code from reading it.
