Only reorganized the structure, no code changes

Main changes:

1. Create "Pages" and "UIComponents" folder inside "components" folder and organize all components into these 2 folders.
2. Rename components belong to Pages components. Such as, in CompanyInformation folder, rename Company.js to CompanyInformationCompany.js, and Contacts.js to CompanyInformationContatcs.js. This will make sure the base components/wrapper will always show in the first place in the folder. So, it will be clear which one is the wrapper and easier to locate/open the wrapper when needed.
