Added ability for html5 target to handle #LIBS

Added the ability for monkey to handle #LIB in html5 target.

Each #LIB will get added in the <head> as a <script src=""></script> tag.

If the #LIB starts with http:// or https:// then the string will be blindly placed in the src="" attrib. 

If a file exists for the give #LIB then this is copied into the build folder and the resulting path is put into the src="" attrib.

If the file doesn't exist then the #LIB path is blindly put into src="" attrib and assumed user will manually handle the import.
