Issue #1999146 by dendie: Remove JS scripts from info files, as they cause errors (and are only needed on one page!)

#786032 Removed .install file that set the preferred method to local compiling on install if the environment passed all the checks. Local compiling has to be selected manually after install now.

* Watchdog messages only appear when at least 1 javascript file has been processed whether successfully or not
* Modified wording
* Removing unnecessary file

* Performance improvements: For checking whether a file has been processed before, only reading the sufficient number of bytes as opposed to
whole file

#632440 Checking for other js modules to prevent collusion and warn the user. Changed the method for detecting js files under sites/default/files/js

Added Compilation Level and Preferred Processing Method admin settings. Added code_url processing method to the module. Improved error handling and logging.

#625142 Using drupal_http_request instead of cURL library now. Added enable/disable switch and javascript file process limit admin settings.
