--User changes

-Add Ctrl+g shortcut for generating a sequence.

--Bug fixes
 -Fix indendation for variations because of type icon.
 -Fix bug when duplicating flame where the new flame wasn't being properly selected.
 -Fix bug where clearing a flame was changing size and quality when it shouldn't have.
 -Fix bug where reading an Xml palette was failing on linux.

--Code changes
 -No longer pad string with null terminator in ReadFile() because std::string already does it.
