Failed test toutput improved
Module script generator fixed

 It used to put system-dependent paths into script files, which resulted in syntactically incorrect string literals on Windows:
 sources += "C:\foo.kt" // \f is wrong here

 Solution: convert paths to system-independent form (forward slashes)
Usinf io.File instead of concatenating paths
Updating to IDEA public preview 122.746
Ignoring proguard errors from xstream
Add labels for extension properties
 #KT-2824 Fixed
Back-end: correct indexes of local variables for double and long
 #KT-3033 Fixed
removed ResolutionStatus.TYPE_INFERENCE_ERROR constant
moved code for successful / failed candidates separation
to ResolutionResultsHandler
OverloadingConflictResolver made singleton
'moreSpecific' fix

if both functions are generic, no need to check receiver and parameters
before recursive call with substituted bounds
'CANNOT_COMPLETE_RESOLVE' error added
complete type inference only for one candidate
(the most specific)
to avoid exponential resolve of value arguments for several candidates
where type inference is incomplete (or depends on expected type)
resolveFakeCall instead of resolveExactSignature
usage changed in tests
'resolveExactSignature' removed
logic for fake value arguments creation
moved to 'resolveFakeCall' method
Refactoring: change signature
Introduced simplest GenerateTests.
Moved test generating code into TestsGenerator, got rid of duplicates.
Regenerated tests.
