Added "tc-" Prefix to CSS Classes

[marvinscharle]

I changed the following css classes, prefixed them with "tc-table-drawer-" to avoid naming conflicts with other CSS class names.

• table-selector -> tc-table-drawer-selector
• table-row -> tc-table-drawer-row
• table-cell-container -> tc-table-drawer-cell-container
• table-cell -> tc-table-drawer-cell

Reason: The class names table-row is very generic and is very likely to produce naming conflicts with other style systems / JS modules. By adding the prefix tc-table-drawer- the name is more specific to this module, since other classes were already prefixed with tc- and therefore less likely to produce name conflicts.
