Summary: support for incremental compilation mode of as3 compiler

Release Notes:
Overview:
The swf10 compiler path has been modified to work compatibly with
flex's "incremental" compilation mode. This is done by only rewriting
an intermediate .as file if the corresponding source .lzx file from
which it came has been modified more recently.
The Flex command shell tool (fcsh), which runs the flex compiler
incrementally, has been modified to run the Laszlo compiler in
incremental mode as well.
A typical debug session works like this
run our modified fcsh:

Details:
The modified files for the flex fcsh tool are checked in to the /vendor branch.
WEB-INF/lps/server/src/org/openlaszlo/compiler/Main.java:
The LZX compiler (lzc) supports two new args, --incremental and --lzxonly
--lzxonly causes intermediate .as files to be written, but the flex
compiler is not called
--incremental causes intermediate .as files to only be written when
the corresponding source lzx files have changed
I removed old code which had a 'incremental' compiler option which was only
settable from
the lps.properties file.
WEB-INF/lps/config/lps.properties:
remove 'incremental' property, it is now an lzc optional arg
WEB-INF/lps/server/src/org/openlaszlo/sc/SWF9External.java:
Add option for "emit_as3_only", which will emit .as files, but not call flex
compiler
Add support for incremental mode, which only rewrites a .as file if the
corresponding .lzx file
is newer.
WEB-INF/lps/server/src/org/openlaszlo/sc/TranslationUnit.java:
Add accessor to find the source lzx filename for a tunit.
WEB-INF/lps/server/src/org/openlaszlo/compiler/SWF9Writer.java
Tests:
1) Compile demos/lzpix/app.lzx using fcsh
2) modify one or more .lzx files in the app
3) rerun compilation in incremental mode ('lcompile' command)
4) verify that modified class or instance-class files are recompiled and linked
