Suggestions to User in bottom status-bar regarding current active object Tools (not added for insert-template tool)

[keshav2010]

Added information regarding object tools which is displayed in the bottom Status-bar, all object tools covered except "Insert Template(V)" tool since I wasn't familiar with it enough.

## UPDATE: this PR is re-created (original PR is closed due to issues as discussed in the comment section there)

now instead of merging content keshav2010:master will use keshav2010:statusBarSuggestionFeature branch which is solely dedicated to this feature.

I've done some very minor changes in the text, but still kept few of them, although they surely make the text a bit longer but I believe these are also essential as, if I talk about my experience with Tiled, it was kind of tough for me to use object tools and often need to refer to online documentation or blind hit some keys on keyboard and so through this PR I tried to put the information that might have benefited me solely. This sure isn't a good decision to see things from my single perspective but I still can't make up my mind as to what part of text I should remove so as to make it shorter, one solution could be, for example changing Left mouse button to "LMB" and likewise use of acronyms at other places but still i think that some users might not be familiar with acronyms.
