Converter for KT-2041: JetRunConfiguration should store its settings in the same format as Java's ApplicationConfiguration to be able to reuse code in JPS

 #KT-1719 fixed

Something like this works now:

===
% PATH="./bin:$PATH" ./sum.ktscript 31 21
31 + 21 = 52

% cat sum.ktscript
#!/usr/bin/env kotlin -script

val a = Integer.parseInt(args[0])
val b = Integer.parseInt(args[1])
println("$a + $b = ${a + b}")
===

KT-2122 Code completion after val with space should not add local variable's name (set priority in completion for local variables and parameters)
 #KT-2122 fixed

still a lot of things to do

 A lot of code relied on these descriptors being mutable. In most cases I managed to work around this,
 but there're still are casts to raw List necessary in one or two places

get rid of JetControlFlowDataTraceFactory

and JetControlFlowDataTraceFactory

added check for unused/uninitialized variables inside local and anonymous functions

- Separate project analysis for IDEA needs: headers + bodies

#KT-2078 fixed

Fixed KT-2072: do not suggest to use type inference in Introduce Variable in case if expression type depends on expected type.

 #KT-2001 fixed

 #KT-2001 fixed

In the most places in frontend identifier is stored in Name class, was in String.
Name has two advantages over String:
* validation: you cannot accidentally create identifier with dot, for example
* readability: if you see String, you don't now whether it is
  identifier, fq name, jvm class name or something else

Name's disadvantage is (small) performance overhead. We have no value types in JVM.
