restore the ll[io]fstream because we need them as wrappers on Windows for wide char paths; on other platforms they are now just typedefs to the std classes

the TC builds failing on these tests.  Appears to be a
conflict/race condition on a temporary file.  Changed the
name of the file.  Should use a tempname()-like API but
this will do for a unit test.

Initial change made LLControlVariable::mPersist an enum, but retained
bool/BOOL public API. setPersist(true) set one value, setPersist(false) set
another, forcePersist() set the third. Per code review, expose enum to public,
make setPersist() (and LLControlVariable constructor, and LLControlGroup::
declareControl(), and all the LLControlGroup::declareMumble() methods, and all
the unit-test dummy declareMumble() method bodies) accept that enum. Remove
forcePersist(). Fix calls to LLControlGroup::declareMumble() accordingly.
Also rename PERSIST_YES to PERSIST_NONDFT, also per code review.

LLControlGroup::declareControl(), declareString() etc. etc. all used to return
BOOL -- which no one ever examines because it unconditionally returned TRUE.
Make it return the (possibly new) LLControlVariable* instead.

back-out the back-out for this branch.  yay.

Backing out this merge that I pushed (prematurely) to the wrong place.

Fix up overriding of --loginuri --loginpage --helperuri

QAR-3119 --grid command-line argument does nothing

Made --grid specifier case insensitive.
Fixed some issues with specifying non-well-known-grids
Fixed some issues with specifying --loginuri, --loginpage and --helperuri

Needs to be changed when IE is checked in, of course.

Now we check the expected credential formats for a given grid against the
format that is typed in, and throw an error if it's invalid.

Show beta grids depending on a settings.xml setting.  for SLE, this will be turned off.  For trunk, it's turned on.
Also, fixed an issue with manual entry of locations into the location dropdown.
