Startup error handling

[knutov]

$ ./app.pl
 core - engine - unknown template engine 'ctpp2', perhaps you need to install Dancer::Template::Ctpp2? at /usr/local/share/perl/5.14.2/Dancer/Template.pm line 17
 BEGIN failed--compilation aborted at ./app.pl line 2.

 $ perl -MDancer::Template::Ctpp2 -MData::Dumper -e 'print Dumper(\%INC)' | grep tpp
 'Dancer/Template/Ctpp2.pm' => '/usr/local/share/perl/5.14.2/Dancer/Template/Ctpp2.pm',

The reason was in missing module, which D:T:Ctpp2 depends, but it's always hard to find the problem with such error messages. In this case D:T:Ctpp2 exists, but was unable start without missing module. Error message tells completely different. May be it's better to change this behavior?

That's a good point, we should improve it. Any suggestions on how it would look like?

[knutov]

At least it's better to write "not installed or was unable to start [because of dependencies]" with current implementation.

But.. If script can not start at all - why Dancer shows his messages instead of perl native errors? It does not make anything better or simple.

Fixed, thank you. :)
