Reword redundant text in Preferences dialog

"RLE encoding" was nearly as bad as "ATM machine".  It has been reworded
as "RLE compression".
Finished work on parameter parsing class
Store image save parameters as one long string

Easier than a variable-length of array of multiple data types.

All INI/preferences handling removed from save functions

In this new build, save parameters (format, color depth, compression,
etc) must be explicitly passed to each save function.  If no parameters
are passed, default values will be used.

This means all INI/preferences handling is done in a prior step by a
separate function.  The save functions themselves no longer have
knowledge of INI crap, which is as it should be.

This was a necessary change for the Batch Process wizard.  Previously,
the individual save functions themselves would read necessary save
format parameters from the INI file at save-time.  Thus, batch
processing is unable to request its own values, unless it does something
hackish like read all INI values, store them, overwrite the originals
with temporary values, perform the batch convert, then reapply the old
values.  I didn't want to go down that route.

Now, the master PhotoDemon_SaveImage function, which acts as a parent to
the format-specific functions, requests a String-type parameter of all
save-related parameters (separated by "|").  If no parameters are
provided, INI values will be read as necessary.

As a bonus, this change allows me to someday add an option for "always
prompt with all possible save options", which some users have requested.
