Keep comments

[BdT141]

This allows for comments to be kept and dumped back into file.

Currently supports:
/* Block comments over multiple lines */
// Single line comments
# Single line hash comments

Does not support in line comments such as:
{
pi: 3.1415 // This is pi
}

Usage:
fp = open("testFile.hjson")
configObject, commentPositions = loadWithComments(fp=fp)
fp.close()

fp = open('newFile.hjson', 'w')
dumpWithComments(fp, configObject, commentPositions)
fp.close()

OR:
fp = open("testFile.hjson")
configObject, commentPositions = loadsWithComments(s=fp.read())
fp.close()

dumpedString = dumpsWithComments(configObject, commentPositions)
fp = open('newFile.hjson', 'w')
fp.write(dumpedString)
fp.close()

Note:
As long as the key names of the loaded dictionary object isn't changed by the program or the order of the items isn't changed, everything should be fine.
