Function Help: Support for doxygen directional param command

[Rosch]

Hi...

Doxygen allows the @param command to have (optional) params to give the direction of the parameter.
(See: http://www.stack.nl/~dimitri/doxygen/co ... l#cmdparam)

So parameter descriptions may look like this:
@param myParam ...
@param[in] myParam ...
@param[out] myParam ...
@param[in,out] myParam ...

Codelite shows doxygen keywords in blue in the function completion help (CTRL+SPACE) but at present cannot detect the param commands with directional parameters. The attached (very simple) patch fixes this so these param commands are now also highlighted in blue by expanding the regex used for detecting doxygen commands.
