* Implemented XML Schema for functionList.xml.
* functionList.xml:
1. new layout of association map;
2. placed `displayName` before `id` attribute where applicable;
3. utilize inline comments;
4. parsers added: 'XML for FunctionList', Assembly, AutoIt3, InnoSetup, PowerShell, KRL, Sinumerik and UniVerse BASIC;
5. parsers improved: C, Java, Batch, Bash, XML and NSIS;
6. replaced `[\t\x20]` with `\h` where possible;
7. using upper case notation for hexadecimal values e.g. `\x7F-\xFF`;
