Prepare for 2013.2 release.
Set correct platform defines for PellesC.
Use $(libcmt) rather than msvcrt.lib directly.

Also, set a correct value for $(libcmt) for PellesC.
[ide] Import build-system to fix broken build.

This is needed for default-build-script and default-build-script-setter
so that the environment options dialog can work.
[win32 jamfiles] Switch to static libc.
Implementation of DEP-0007, less compatibility changes.
Implementation of DEP-0007, with compatibility changes.
Collections test suite was incorrect for “element”: the return value does not need to be the element type of the collection if “default:” is used.
Collections test suite was too strict with add! and remove!: OD implements them on <collection>, not just <sequence>.
Implementation of DEP-0007 that works with existing (modified) tests and repeated slots. “-with-fill” classes removed.
More correct array handling in library code.
Corrected implementation of “element” to allow element-not-found default of different class than element type.
Removed default value for “default-fill:” keyword argument to “limited”. Neither the DRM nor the DEP calls for it.
Fixes shadowing definition of element-type and element-type-fill.
Correctly initializes element-type-fill of concrete limited collection classes.
Fixes <stretchy-vector> resizing to employ the element-type-fill when increasing collection size.
Creating limited <string> results in limited <byte-string>.
Removed redundant code.
Added tests.
