Add BuildHeadlessProgram method for specifying headless program construction
Add BuildUnitTest method for specifying unit test program construction
Add BuildDependencyLibrary method for specifying dependency library construction

Change command strings to be less verbose by default with build/no_verbose.py
Add color utilities in build/color.py
Extract string utilities to build/string.py

Change GlobRecursive functions to use cwd over specifying directory in pattern
Change GetGitInfo to method
Add name_prefix attribute getter inside GetGitInfo method
Move functionality of build/common_compiler_flags to tools/scripts_flags.py
Update platform tools to use tools/script_flags.py
Remove obsolete platform tools
Add .gitignore entries for scons artifacts
