Universally quantified types (parsing and inference)

Bug fix in reference marking

Fixed some bugs in generics

- unused dynamics in where/let clauses do not cause a rule doesn't match
  error in overloading.icl instead they are ignored
- default behaviour changed e.g.

f (i :: Int, j :: Int) = abort "Int"
f (r :: Real, s :: Real) = abort "Real"
f _ = abort "stop"

The compiler first matched on the tuple and then did the dynamic pattern
matches. But the last match did not call the last (default) alternative if it
did not match.
- some small changes

definition module spetiul
f :: a | == a special a=Int

  class c m :: *(m Int) -> (m Int)
is not accepted anymore

fromString is not yet supported
some error handling improved
parial instances are temporary disabled

changed Declaration type
fixed crash when macro appears only in dcl module
added make with caching in 'main'
use BoxedIdent in hashtable

incorrect module and type index when the symbol is not defined
or used with incorrect arity. This prevents a crash later in
the compiler when the type is used again when expanding type
synonyms resulting in an 'index out of range' error.

Tested with compiling Object IO and butstrapping.

- type variables
- passing a list of directly imported dcl modules by an icl modules

checking of a whole dcl module component --> now cyclic module dependencies
should work

"context restriction not allowed for fully polymorph instance" and
"context restriction equals instance type"

"PA_BUG" for the same purpose. MW removes his macro _untertaenig_ in favour
of Sjaaks version

   in "convertCasesOfFunctionsIntoPatterns" and "collectVariables")
 - new switch "SwitchUniquenessBug" in module checksupport
 - several bugfixes

    (new module: comparedefimp)
- implemented array patterns. Further work: arrays are in lazy context (should be strict),
    currently only one dimensional arrays
- optimised memory usage for explicit imports
