Minor: Documentation for ini_getbool mentions nonexisting parameters

[tinus-github]

Xcodes analyser notes that the doxygen code for ini_getbool mentions the parameters Buffer and BufferSize, which are not present in the function definition, which appears to be true:

/** ini_getbool()
[...]
 * \param Buffer      a pointer to the buffer to copy into
 * \param BufferSize  the maximum number of characters to copy
[...]
int ini_getbool(const TCHAR *Section, const TCHAR *Key, int DefValue, const TCHAR *Filename)

I'm not really sure how to note that but I created a pull request here: #4
