If the user has python2.7 installed but it's not the default interpreter
on their system, they might get confused when they invoke the parser and
get a message about needing to install 2.7 even though they already have
it installed. Add some instructional messages about this situation to
the 2.6 invocation warning message as well as the README.

The parser now requires Python 2.7 so that 2.7-specific features can be
leveraged. Update the README to reflect this.

Ram dumps are now being generated for 64-bit ramdumps. Update the
parser to account for this.

After a crash, ramdumps may be collected for analysis. The ram
parser is a tool to aid in analysis of these dumps. The script
extracts useful information from the dumps to help with debugging.
Please see the README for full details.
