Integrated compile and run commands for most languages.

Compile and run should work out of the box for most languages. Also added a
warning marker, renamed `compile_command` and `run_command` tables to
`compile_commands` and `run_commands`, respectively, and renamed `error_details`
to `error_patterns`, changing its structure to just hold patterns.
