ObjectScript Code

fix wrong # of args issue

update versions

hacks to support windoze UNC style paths, ie `\\server\share\blah\blah`

work-around for bug in `String#split()` (or if not a bug, at least a deviation from how it works in javascript, and I'd prefer to stay compatible(ish) with javascript)

1) clean up some imports in `org.oscript.jawin`
2) script function's `castToString()` should include argument names
3) fix problem with debugger

checkin changes from last night (internet is down at home):

now instead of converting a `for` loop to a `while` loop, the opposite is done. This is needed to propery evaluate the post-loop-expression in the case of a `continue`.

need to catch and rethrow java exceptions, so that they can be caught by script code

fix problem with detecting changed plugins... was getting confused by a rel_x.y.z branch listed in a log message from merging from another mainline. Only filter release branches if there is no leading whitespace on the line

fixes this issue with interpreted (but not compiled) code:
{{{
ObjectScript 2.11.0 (r1995)
os> [1,2,3][1..2]
java.lang.NullPointerException
at oscript.data.OArray.idx(OArray.java:316)
at oscript.data.OArray.elementsAt(OArray.java:374)
}}}

not too suprisingly, this is the one test case that is commented out (because `[1,2] != [1,2]`).. need to add a test case for this somehow.

add `pkg.xml.encode()` utility, and make `pkg.fs` more consistent w.r.t. accepting files or paths
