There is no code added or removed. All changes are to make Text editor code look more like the rest of ImHex.
- All member variable names that used a convention like in `mFieldVariable` were switched to the common ImHex convention of `m_fieldVariable`.
- All member function names that used pascal case were switched to the common ImHex convention of camel case.
- All int, unsigned int, unsigned long ... were switched to int32_t, uint32_t, uint64_t,... I used those because TextEditor has no access to the ImHex headers where the types are defined.
- Local variable names that were cryptic were given more descriptive ones.
- Other changes include a few fixes from cppCheck mostly for variable scope.
