    Merge pull request #193 from jvprat/class_tostring

    Merge pull request #240 from urzds/fix/lapp-convert-defaults

    lapp: Convert default values using the associated converter function
    Merge pull request #242 from tjachmann/workaround-for-pretty.load-error

    Workaround for error in pretty.load with a C hook

    pretty.load errors out, if a C hook function is installed (Lua 5.1). Reason: \ 
debug.gethook() returns a string as first return value in this case.  Then \ 
debug.sethook complains about the first argument being a string not a function.
    lapp: Convert default values using the associated converter function

    Also uses quite some hack to catch errors during conversion of default values.
     This prevents the application from quitting, if the value provided as default
     would be invalid in the current context, while the value provided on the
     command line is valid.

    Also handles -h and --help early, before parsing command line arguments
     Otherwise it would be impossible to show the help, if conversion of the
     default value of some argument fails.
