existsFile is deprecated, and now using fileExists instead

replaced ..colon with 0..colon, because ..b is deprecated to 0..b.

cuchar is deprecated, thus replaced with char

implicit conversion from string to cstring, thus added the cast to avoid CStringConv compile errors in the future

type pragmas follow the type name; this form of writing pragmas is deprecated

See corresponding Defect; DivByZeroError is deprecated, thus use DivByZeroDefect instead

added the pid_kill function, which will send a SIGKILL to the specified PID.

added pid_kill procedure for killing the specified pid. This opens the process and then terminates it. Raises an OSError for an error

Do to casting errors, i've added casts to where I was getting them.

i've added some checks for OpenProcess return variable.

added the pid_kill proc to the psutil.nim file, also exporting the platform so user can access all the function without needing to do "psutil/platform_linux" or "psutil/platform_windows"
